    HOWARD, Circuit Judge. In the course of a lengthy roadside
    stop, Illinois state troopers discovered more than 400 pounds of
    marijuana in a 1957 Volkswagen pickup truck that defendant Michael
    Hornbecker had been towing across the country. Hornbecker subsequently
    pleaded guilty to conspiring to distribute marijuana, but reserved his
    right to appeal the district court's earlier denial of his suppression
    motion. Hornbecker acknowledges that he voluntarily signed a consent-
    to-search form approximately 23 minutes after he was stopped, but argues
    that the ensuing search was rendered unlawful by the troopers' prior
    Fourth Amendment violations.     We disagree and accordingly affirm.
    I.   Background
    We take our factual recitation from the record of the
    proceedings below, which included the introduction into evidence of a
    videotape of the search made by the Illinois state police. On August
    16, 1998, at just prior to 7:58 p.m. (according to the timer on the
    police videotape), Illinois State Trooper John Rugen stopped Hornbecker
    as he was heading east on Interstate 80 in LaSalle County, Illinois.
    Hornbecker was driving a 1987 Chevrolet pickup with California license
    plates and towing a flatbed trailer on which sat the Volkswagen. Rugen,
    who was then a member of an Illinois state police drug interdiction unit
    that used routine traffic stops to further its purposes, told Hornbecker
    that he had been stopped for driving seven miles per hour over the
    applicable speed limit and for having a cracked windshield.
    As Rugen was asking Hornbecker for his license and
    registration, he also inquired about Hornbecker's travel itinerary.
    Hornbecker replied that he was driving from southern California to New
    -2-
    Hampshire to sell the Volkswagen. Rugen found this answer fishy because
    the Volkswagen did not appear sufficiently valuable to warrant a cross-
    country drive to sell it.    He wondered whether Hornbecker might be
    transporting drugs in the Volkswagen because southern California is a
    drug source region and because the Volkswagen's unusual body style
    looked as though it contained a voluminous, difficult-to-access area
    behind the cab and between the bed and the undercarriage. Despite (or
    perhaps because of) his suspicion, Rugen's affect was friendly, even
    gregarious. Rugen informed Hornbecker that he was only going to give
    him a warning. While returning to the cruiser to write the warning,
    Rugen stepped up on the flatbed trailer so that he could further survey
    the Volkswagen's atypical body structure.
    Rugen   radioed   for   a   check   on   Hornbecker's   license,
    registration, and criminal history. Seconds later, Rugen radioed for
    a drug-sniffing dog to be brought to the scene. Almost immediately
    after requesting the dog, Rugen learned that Hornbecker had a valid
    driver's license and registration and no outstanding warrants or
    criminal history. Nevertheless, Rugen did not complete Hornbecker's
    warning and send him on his way.      Instead, at just after 8:02 p.m.,
    Rugen returned to Hornbecker's car to ask whether Hornbecker had papers
    verifying ownership of the Volkswagen. Hornbecker replied that he did
    and, because the papers were in the Volkswagen, exited the Chevrolet to
    retrieve them.
    As the two stood next to the old pickup, Rugen amiably and
    off-handedly questioned Hornbecker about it. Pointing to the enclosed
    area behind the cab, Rugen asked, "What is this, storage under here?"
    -3-
    Hornbecker replied, "That's the way it came, right? . . . The motor and
    gas tank is here." Hornbecker then entered the Volkswagen's cab and
    began to search for its paperwork. Rugen peered beneath the Volkswagen
    and noticed that the engine was not just behind the cab, as Hornbecker
    had indicated, but was all the way to the rear. Rugen returned to his
    cruiser and took a seat inside, while Hornbecker went back to the
    Chevrolet to retrieve his briefcase, where he now said he thought the
    paperwork was.
    Between 8:06 and 8:07 p.m., Trooper Craig Graham arrived with
    a drug-sniffing dog. A few seconds later, Hornbecker walked back to
    Rugen's cruiser and told Rugen that he had not yet found the requested
    paperwork, but insisted he had it with him. Hornbecker then returned
    to his vehicles and resumed his search. Meanwhile, Graham approached
    Rugen's cruiser. Rugen told Graham that "this thing looks screwed up,"
    explaining that the Volkswagen's engine was not where Hornbecker had
    said it was and expressing concern about the large, inaccessible space
    behind the truck's cab. Graham began to examine the Volkswagen, peering
    into its cab with a flashlight and stepping up on the trailer to look
    into its bed. He then returned to the driver's side of Rugen's vehicle,
    signaling that he would walk the dog around the tow trailer. Graham
    noted that another state trooper had "got one just like that. It was
    on the back of a Ryder truck."
    Apparently now having located the Volkswagen's papers, at
    shortly after 8:08 p.m. Hornbecker brought them to Rugen, who invited
    Hornbecker to sit with him in the cruiser as he completed the warning.
    Rugen informed Hornbecker that Graham would be walking the dog around
    -4-
    Hornbecker's vehicles and asked whether Hornbecker was carrying anything
    illegal. Hornbecker replied that he was not. As Graham conducted the
    drug sniff, Rugen engaged in friendly banter with Hornbecker, asking him
    a number of questions about the Volkswagen and the vintage car trade.
    The dog did not alert. Shortly after 8:11 p.m., Rugen handed Hornbecker
    a written warning, returned all of his documents, and told him, "You're
    all set to go, free to leave." Hornbecker responded by asking Rugen
    about the effect of the warning. Rugen explained that it would show up
    in the computer if Hornbecker were stopped again in Illinois. Rugen
    again told Hornbecker that he was "all set to go," but then immediately
    asked whether he might take a look "at that engine compartment there,"
    quickly explaining "I have never seen a truck like that before . . . .
    'Course I'm only 31 years old." Hornbecker replied "You certainly may."
    At just prior to 8:12 p.m., Rugen and Graham went to the rear
    of the Volkswagen (where Rugen understood the engine to be despite
    Hornbecker's earlier indication that it was behind the cab) and
    attempted to pry open the engine compartment's access door. Hornbecker
    said something about a screwdriver, to which Rugen responded, "Oh, it
    takes a screwdriver? I got a screwdriver." He retrieved one from his
    cruiser, opened the compartment door, and (with Graham) peered inside.
    After completing their examination of the engine compartment,
    the troopers closed its access door and began to examine the remainder
    of the Volkswagen's exterior, tapping it, banging on it, and asking
    Hornbecker questions about it.       At all times, the troopers were
    friendly.    Rugen conveyed what was almost certainly a contrived
    fascination with the "big ole truck," at one point stating he might have
    -5-
    "to buy one of these." At around 8:14 p.m., Rugen asked Hornbecker if
    he could look in the Volkswagen's cab. Although Hornbecker's response
    is inaudible, the videotape suggests that Hornbecker consented.1      A
    couple of minutes later, Rugen asked Hornbecker for the key to the gas
    port. Hornbecker replied that, like the engine compartment, the port
    could be accessed with a screwdriver. Rugen pried open the gas port,
    looked inside, and stated, "[T]his is not right." Rugen explained to
    Hornbecker, who himself had voluntarily removed some items from the
    truck's bed, that he was concerned about the unaccounted-for space in
    the area behind the cab. At just after 8:19 p.m., Rugen returned to his
    cruiser and radioed a request that another trooper bring him a device
    that measures the density of inaccessible areas. Rugen then returned
    to Hornbecker, reiterated his concern about the area behind the cab, and
    told Hornbecker that he wanted to bring somebody to the scene with a
    device for measuring spaces. Rugen subsequently asked Hornbecker to
    sign a form consenting to a search of the Volkswagen. At approximately
    1
    At the suppression hearing, the following exchange took place
    during cross-examination of Trooper Rugen by counsel for the
    defendant:
    Q: And now you're asking if you can look in the cab?
    A: Yes, after again asking about that area of concern.
    Q: And after looking underneath the vehicle?
    A: Correct.
    Q: Okay. And the reason you asked if you could look in the
    cab is that you didn't have permission by asking him to
    look in the engine compartment to look in the cab?
    A: Correct.
    Q: And he said, okay, yes, look in the cab?
    A: That's right.
    Q: So you look in the cab?
    A: Yes, ma'am.
    The district court found that Hornbecker had consented to Rugen's
    request to look in the cab.
    -6-
    8:20 p.m., nearly 23 minutes after being pulled over, Hornbecker
    voluntarily signed the form. About an hour and a quarter later, the
    troopers breached the space behind the cab and discovered the marijuana.
    Illinois authorities subsequently charged Hornbecker with
    cannabis trafficking, but Hornbecker prevailed on a pretrial suppression
    motion which argued that the troopers had violated his Fourth Amendment
    rights. The state unsuccessfully appealed that ruling and eventually
    abandoned the prosecution.      Meanwhile, as the state's appeal was
    pending, a federal grand jury sitting in Massachusetts indicted
    Hornbecker    for   participating   in    a   multi-participant    marijuana
    distribution conspiracy. Hornbecker subsequently filed a motion to
    suppress in the federal case, contending that his eventual written
    consent to the search was vitiated by the fact that Rugen began
    violating his Fourth Amendment rights at around 8:02 p.m., when Rugen
    continued to detain him despite learning that Hornbecker's license and
    registration were valid and that there were no outstanding warrants
    against him.
    Hornbecker presented two arguments in support of this
    constitutional claim.     First, he asserted that his detention from
    approximately 8:02 p.m. until approximately 8:11 p.m. (when Rugen gave
    him the warning, returned his documents, and told him that he was free
    to go) was unreasonable because Rugen lacked justification to continue
    the traffic stop after learning that Hornbecker was not wanted, had a
    valid license, and was driving a registered vehicle.              Second, he
    maintained that the troopers' conduct was unreasonable between
    approximately 8:11 p.m. and approximately 8:20 p.m. because it involved
    -7-
    encroachments beyond the engine compartment search to which he
    consented. In pressing this point, Hornbecker cited cases in which
    warrantless searches justified by consent were held unlawful because the
    challenged intrusions exceeded the scope of the consent given, e.g.,
    United States v. Infante-Ruiz, 
    13 F.3d 498
    , 505 (1st Cir. 1994), but
    primarily argued that the written consent he eventually provided was
    ineffective because it was immediately preceded by a protracted period
    of unlawful detention.       The district court rejected Hornbecker's
    arguments. The court opined that Hornbecker's detention prior to 8:11
    p.m. was reasonable because Illinois law explicitly permits routine
    traffic stops to last up to 15 minutes. The court further ruled that
    no constitutional problem was presented with respect to the period
    between 8:11 p.m. and the time Hornbecker signed the consent-to-search
    form because Hornbecker had been told that he was free to leave but
    consented to stay, to let the troopers conduct certain limited searches,
    and to answer the troopers' questions.           Yet in reaching its
    determinations, the court, in dicta, sided with Hornbecker and against
    the government on whether, prior to obtaining Hornbecker's written
    consent to a search, the troopers had a reasonable basis under Terry v.
    Ohio, 
    392 U.S. 1
    , 18-20 (1968), to detain Hornbecker on grounds other
    than speeding and driving with a cracked windshield: "[A]fter the
    conclusion of the legitimate traffic stop [which in the court's
    estimation occurred at 8:11 p.m.], the police would have violated the
    Fourth Amendment [by continuing to detain Hornbecker], and justified the
    suppression prayed for, had it not been for the fact that Hornbecker
    consented [to remain on the scene]."
    -8-
    II.   Discussion
    Hornbecker asserts the same arguments on appeal that he
    advanced in the district court. He contends that his detention was
    unlawful between approximately 8:02 p.m. and approximately 8:11 p.m.
    because it was unrelated to the reasons for the traffic stop and
    unsupported by a reasonable suspicion that he was engaged in some other
    unlawful conduct. With respect to the period between approximately 8:11
    p.m. and 8:20 p.m., his position remains a bit unclear, but we shall
    assume that he is challenging the troopers' conduct on both search and
    seizure grounds. See pages 7-8, above. In any event, Hornbecker's
    overall argument is straightforward and very capably presented: the
    district court erroneously regarded as effective his written consent to
    the search which yielded the marijuana because it failed to appreciate
    that the troopers' prior conduct violated the Fourth Amendment. We
    disagree.
    We start with the latter of the two temporal periods in
    question and with Hornbecker's largely unelaborated suggestion that
    suppression remedy is warranted by one or more unlawful searches which
    took place in this interim. We reject the suggestion. The district
    court made express factual findings that Hornbecker consented to the
    troopers' searches of the Volkswagen's engine compartment and cab.
    Hornbecker does not challenge these findings, to which we owe deference.
    See United States v. Bunnell, 
    280 F.3d 46
    , 48-49 (1st Cir. 2002). Nor
    does he argue that the opening of the gas port was an unlawful search.2
    2
    We train our focus on these three penetrations of interior
    vehicular spaces because Hornbecker does not develop an argument that
    the troopers' other conduct between approximately 8:11 p.m. and
    -9-
    Finally, Hornbecker does not explain why, even if one or more of these
    searches was unlawful, we should order the suppression of evidence found
    over an hour later in the course of a different search.
    We also reject Hornbecker's challenge to the district court's
    conclusion that no Fourth Amendment detention occurred between
    approximately 8:11 p.m. and approximately 8:20 p.m. To reiterate, the
    court found that Hornbecker was not detained (and thus not "seized")
    during this period because he was twice told that he was free to go but
    consented to stay and to comply with the troopers' various requests.
    Hornbecker's brief cites no authority discussing the line between de
    facto seizures and non-coercive police questioning. In any event, the
    court's ruling, to which we must once again defer, Bunnell, 
    280 F.3d at 48-49
    , is sustainable because Hornbecker was twice told that he was free
    to leave and twice asked whether he consented to searches that took
    place during the period in question. Although few people actually feel
    approximately 8:20 p.m. constituted a search and the law points strongly
    in the other direction. See New York v. Class, 
    475 U.S. 106
    , 118 (1986)
    (areas inside automobile within plain view of persons on outside are not
    "subject to a reasonable expectation of privacy"); Texas v. Brown, 
    460 U.S. 730
    , 739-40 (1983) ("It is . . . beyond dispute that [the
    officer's] action in shining his flashlight to illuminate the interior
    of [defendant's] car trenched upon no right secured . . . by the Fourth
    Amendment.") (plurality opinion of four Justices; other five Justices
    concurring in the judgment and disagreeing on unrelated issues); 
    id. at 740
     ("Likewise, the fact that [the officer] changed his position and
    bent down at an angle so he could see what was inside [defendant's car]
    is irrelevant to Fourth Amendment analysis.") (brackets and internal
    quotation marks omitted); United States v. Muniz-Melchor, 
    894 F.2d 1430
    ,
    1433-36 (5th Cir. 1990) (tapping on exterior of large propane tank
    mounted in defendant's truck did not constitute a search); see also 1
    Wayne R. LaFave, Search and Seizure, § 2.5(c) (1996) (indicating that
    examinations by natural senses of vehicular exteriors and vehicular
    contents do not constitute searches absent a physical intrusion into the
    vehicle).
    -10-
    free to walk away while being questioned by a police officer, the Fourth
    Amendment is not implicated unless, viewed objectively, the officer's
    conduct communicates an intention to use official authority to restrain
    the individual's freedom of movement. See United States v. Cardoza, 
    129 F.3d 6
    , 14-16 (1st Cir. 1997) (collecting cases). The court did not err
    in declining to find such a message in the troopers' words and conduct.
    The success of Hornbecker's appeal thus depends on our
    determining that Rugen violated Hornbecker's Fourth Amendment right to
    be free from an unreasonable seizure by detaining him until   8:11 p.m.
    (approximately thirteen minutes into the stop) instead of turning him
    loose at or shortly after 8:02 p.m., when he learned that Hornbecker was
    not wanted and that Hornbecker's license and registration were valid.
    The district court seems to have upheld the detention during this period
    on the ground that, in Illinois, a legal traffic stop is never
    unlawfully protracted if it is concluded within 15 minutes. See p. 7,
    above. Hornbecker says that this all-or-nothing proposition is at odds
    with Florida v. Royer, 
    460 U.S. 491
    , 500 (1983) (plurality opinion)
    (observing that "an investigative detention must be temporary and last
    no longer than is necessary to effectuate the purpose of the stop").
    Because the government does not defend this basis for the court's ruling
    and because there exist narrower grounds to support the court's
    judgment, we do not address matters related to the Illinois 15-minute
    rule. See, e.g., United States v. Doe, 
    61 F.3d 107
    , 111-12 (1st Cir.
    1995) (permitting affirmation of a district court's suppression ruling
    on any ground made manifest by the record).
    -11-
    Hornbecker and the government agree that Rugen detained
    Hornbecker between 8:02 p.m. and 8:11 p.m., and that the lawfulness of
    the detention is appropriately analyzed under the Terry line of cases.
    Hornbecker and the government also concur that, because most of the
    period between Rugen's request for the Volkswagen's papers and his
    completion of the written warning was attributable to Hornbecker's
    initial inability to locate the papers, whether Rugen lawfully detained
    Hornbecker during this period essentially depends on whether Rugen's
    request to inspect the papers was objectively reasonable under the
    circumstances. See, e.g., Ornelas v. United States, 
    517 U.S. 690
    , 695-
    697 (1996) (recognizing that the lawfulness of a detention, whether a
    Terry stop or a full custodial arrest, is determined by a fact-specific
    application of a legal standard designed to help courts assess whether
    the police action was objectively reasonable).3
    Citing interests in regulating motor vehicles that travel the
    public highways and in deterring the trafficking of stolen vehicles, the
    government argues that, just as law enforcement officers may reasonably
    ask for a motorist's license and registration papers during a routine
    3
    Judge Coffin's dissenting opinion can be read to suggest
    that, even if Rugen reasonably asked for the Volkswagen's
    paperwork, the detention of Hornbecker during the approximately
    three-minute period between Rugen's receipt of the paperwork and
    his issuance of the written warning was unreasonable because it
    was prompted by Rugen's desire that Graham complete the canine
    sniff. We respectfully disagree. By the time Hornbecker produced
    the Volkswagen's paperwork, Rugen's initial suspicion had been
    bolstered by Hornbecker's misleading answer about the space behind
    the cab and Graham's indication to Rugen that another trooper had
    recently discovered hidden contraband under similar circumstances.
    See, p.4, above. We think these additional grounds for suspicion
    gave Rugen justification to extend the detention long enough to
    permit Graham to complete his walk-around.
    -12-
    traffic stop, they may also always reasonably ask for the registration
    or ownership papers of a vehicle being towed.       Alternatively, the
    government contends that Rugen's request to see the Volkswagen's papers
    was reasonable under the particular facts of this case. Hornbecker
    disagrees that the police may always ask to see papers pertaining to a
    towed vehicle, pointing out that a motorist need not even possess the
    papers of such a vehicle because it is not being driven. And he resists
    the government's case-specific argument by arguing that Rugen lacked a
    reasonable suspicion that the Volkswagen was an instrument of illegal
    activity. We do not resolve the broader dispute because, in the context
    presented, Rugen's request to see the Volkswagen's papers was
    reasonable.4
    We acknowledge at the outset that, although the district
    court did not explicitly consider whether the request to see the
    Volkswagen's papers was reasonable in context, our conclusion that it
    was may conflict with the court's dicta that Rugen had no basis to
    detain Hornbecker for reasons unrelated to the traffic stop. After all,
    the request came after Rugen learned that there was no outstanding
    warrant for Hornbecker and that Hornbecker's license and registration
    were valid; it thus prolonged the detention beyond the point at which
    4
    In his testimony at the suppression hearing, Rugen indicated that
    he was proceeding on the assumption that, during a routine traffic stop,
    he always may ask to see the papers of a vehicle being towed. Of
    course, whether Rugen's subjective understanding was correct does not
    inform the Fourth Amendment inquiry. What matters is whether Rugen's
    request was objectively reasonable under the circumstances. See Whren
    v. United States, 
    517 U.S. 806
    , 809-19 (1996). For this same reason,
    it is immaterial whether Rugen subjectively believed that he had grounds
    to detain Hornbecker between 8:02 p.m. and 8:11 p.m. for a reason other
    than his belief that he always is entitled to ask for the papers of a
    vehicle being towed.
    -13-
    it might otherwise be expected to have concluded.5 But we are obliged
    in these circumstances to reach our own, independent judgment about the
    reasonableness of the request. Ornelas, 517 U.S. at 697-98 (holding
    that ultimate determinations of reasonable suspicion are subject to
    independent appellate review).
    In assessing the reasonableness of Rugen's request, we "must
    balance the nature and quality of the intrusion on personal security
    against the importance of the governmental interests alleged to justify
    the intrusion." United States v. Chhien, 
    266 F.3d 1
    , 6 (1st Cir. 2001)
    (citations and internal quotation marks omitted), cert. denied, 
    534 U.S. 1150
     (2002); see also United States v. Stanley, 
    915 F.2d 54
    , 55 (1st
    Cir. 1990) (Terry stops "must be justified by reasonable suspicion
    proportional to the degree of intrusion"). Keeping the balance true
    requires "a practical, commonsense judgment based on the idiosyncracies
    of the case at hand" and an assessment whether the officer's actions
    "were fairly responsive to the emerging tableau." Chhien, 
    266 F.3d at 6
     (citations omitted).    It also requires "deference . . . to the
    experienced perceptions of the officers," United States v. Woodrum, 
    202 F.3d 1
    , 7 (1st Cir.), cert. denied, 
    531 U.S. 1035
     (2000), because
    factual circumstances that seem innocuous to a layman might well appear
    suspicious (and reasonably so) to the seasoned eye of law enforcement
    professionals, see Ornelas, 
    517 U.S. at 700
     ("To a layman the sort of
    loose panel below the back seat armrest in the automobile involved in
    this case may suggest only wear and tear, but to [the officer], who had
    5
    This is the premise of Hornbecker's argument regarding the 8:02
    p.m. to 8:11 p.m. time frame and we assume its validity arguendo for
    purposes of our analysis.
    -14-
    searched roughly 2,000 cars for narcotics, it suggested that drugs may
    be secreted inside the panel.").
    Guided by these principles, we conclude that Rugen's request
    to see the Volkswagen's papers was lawful. In our view, continuing the
    detention of an already lawfully seized motorist for the short period
    of time that it typically takes to locate and produce vehicle
    registration or ownership papers (even if the papers are contained
    within a vehicle being towed and thus not within immediate reach) is a
    relatively   slight   intrusion    on    Fourth   Amendment   interests.
    Consequently, in assessing whether, as of 8:02 p.m., the facts gave
    Rugen "a particularized and objective basis for suspecting [Hornbecker]
    of criminal activity," Ornelas, 517 U.S. at 696 (describing the
    "reasonable suspicion" required to justify a Terry stop) (citation and
    internal quotation marks omitted), we are somewhat less demanding than
    we would be if we were evaluating the lawfulness of a Terry stop that
    resembled a full, custodial arrest, see, e.g., Chhien, 
    266 F.3d at 6
    (recognizing that the inquiry into whether the facts adequately
    supported a Terry stop is informed by the nature and quality of the
    intrusion); Stanley, 
    915 F.2d at 55
     (similar); cf. United States v.
    Finke, 
    85 F.3d 1275
    , 1280 (7th Cir. 1996) (concluding, in a case
    challenging an officer's continuation of a traffic stop in order to
    conduct a criminal history check on the motorist, that less than
    overwhelming grounds for suspecting the motorist of drug trafficking
    were nonetheless sufficient to warrant the brief period of extra
    detention required to conduct the check).
    -15-
    When all is said and done, the facts here were sufficient to
    satisfy the demands of Terry. Certainly, Rugen reasonably suspected
    that Hornbecker was lying when he stated that he was towing the
    Volkswagen from California to New Hampshire to sell it. One does not
    need to have expertise in the value of vintage automobiles (and Rugen
    admitted at the suppression hearing that he had no such expertise) to
    wonder how such a trek to sell a vehicle seemingly worth no more than
    a few thousand dollars6 could be cost effective.        And once Rugen
    reasonably suspected that Hornbecker was lying about the purpose of his
    trip, the evidence that Hornbecker hailed from a known drug source area
    and was hauling an unusual vehicle with a voluminous, inaccessible
    cavern inside its body structure justified Rugen's brief continuation
    of the detention while Hornbecker attempted to produce the Volkswagen's
    paperwork (especially when we factor in the deference we owe to Rugen's
    training and experience).7 Cf. United States v. Sowers, 
    136 F.3d 24
    ,
    27-28 (1st Cir. 1998) (passenger's lack of identification papers,
    nervousness of driver and passenger, and fact that driver and passenger
    told conflicting stories sufficient to prolong their detention);
    6
    There was evidence that Hornbecker had purchased the truck not
    long before for $2200.
    7
    Hornbecker argues that the request for paperwork was a pretext
    designed to delay the detention until a drug-sniffing dog could be
    brought to the scene. Whether or not he is correct, his argument is
    beside the point. So long as the request could help confirm or dispel
    suspicions reasonably raised by Hornbecker's doubtful explanation for
    his trip in the mind of an objectively reasonable law enforcement agent,
    Rugen's actual purpose in making the request does not matter. See
    Whren, 
    517 U.S. at 809-19
    . Here, a reasonable officer might have asked
    to see the paperwork because the absence of such paperwork would make
    the proffered explanation for the trip even more suspicious. After all,
    a private sale of an automobile usually involves a transfer of ownership
    documentation.

    Stanley, 
    915 F.2d at 56-57
     (fact that defendant was alone in car late
    after midnight in area frequently used for illegal drug activities, was
    leaning over the vehicle's illuminated center console, and appeared to
    try to hide something when he saw officer sufficient to warrant the
    person's detention).
    III.   Conclusion
    We agree with Judge Coffin that this is a close case    and
    appreciate especially his forceful and eloquent admonition that the
    lawfulness of contested searches and seizures be assessed realistically
    and holistically. And we are not blind to the fact that the troopers,
    and especially Trooper Rugen, may well have manipulated Hornbecker into
    relinquishing Fourth Amendment rights by means of ingratiating
    conversation and insincere friendliness. But so long as manipulative
    behavior does not cause us to question whether the relinquishment was
    in fact voluntary (e.g., an abuse of office such as the actual or
    threatened use of force), it is "reasonable" within the meaning of the
    Fourth Amendment. See Schneckloth v. Bustamonte, 
    412 U.S. 218
    , 222-27
    (1972). As a general matter, insincere friendliness which successfully
    induces a criminal suspect to willingly answer questions and/or consent
    to a search does not, without more, cause us to question whether the
    suspect's response is "voluntary." Cf. id. at 226 (listing factors
    typically bearing on the factual "voluntariness" inquiry).        Such
    behavior   is   thus   not   constitutionally    offensive.
    For the reasons we have stated, we do not believe that
    Hornbecker's Fourth Amendment rights were violated in connection with
    -17-
    the search that led to the discovery.         We therefore affirm his
    conviction and sentence.

    Dissent follows.

    COFFIN, Senior Circuit Judge (Dissenting). I write separately
    to indicate my unease at the enhanced opportunity permitted by the
    court's approach for stretching the limits of both Terry stops and
    consents to limited search under escalating pressures.              Reviewing
    all the circumstances of this case, I find that each step in the
    investigative process was precariously close to the constitutional
    line   and   that   the   totality   of     these   close   calls   points   to
    impermissible excess.
    The initial stop, for exceeding the speed limit and having a
    cracked windshield, is not at issue here.           The first close call is
    the court's holding that Trooper Rugen was justified in requesting
    that appellant procure registration or ownership papers for the
    Volkswagen, despite the fact that two minutes earlier, at 8:00
    p.m., he had received word that appellant’s license was valid and
    that there were no outstanding warrants and no criminal history.
    Without an objectively reasonable suspicion, the detention would
    have been invalid.        The objectively reasonable basis, the court
    decides, was the unlikelihood of a thirty-year-old Volkswagen
    pickup truck being worth the cost of being towed across the United
    States for sale in New Hampshire, the fact that southern California
    was known as a source for drugs, and Rugen’s curiosity about the
    space behind the cab. The court so finds despite Rugen’s testimony
    that he had no reasonable suspicion at the time he ordered a canine
    search at 8:00 p.m. and the district court’s statement that, as of
    8:11 p.m., "the police had plenty of curiosity but no 'articulable
    suspicion.'"
    -19-
    If    this   detention     falls   within    permissible     limits,    its
    justification is at best marginal.               To elevate Rugen's vague
    hunches to the level of a particularized or articulable suspicion
    of criminal activity is a stretch.
    Next is Trooper Rugen's admitted delay in finishing his
    paperwork in order to allow the dog to complete its walk.                  Rugen
    asked no fewer than fifteen questions of appellant during this
    delay, which he characterized as "just making conversation."
    See United States v. Pruitt, 
    174 F.3d 1215
    , 1221 (11th Cir. 1999)
    (irrelevant "'fishing expedition'" questions violated Terry).                 It
    was not until 8:11 p.m., after the canine had finished its walk and
    eleven minutes after Rugen had received clearance on appellant,
    that Rugen handed appellant his license and registration and said
    he was "free to leave."
    Yet just three seconds after giving him clearance to leave,
    Trooper Rugen asked if appellant "would mind" if he looked at the
    engine    compartment.      I    suspect   that    the   close    coupling    of
    permission to leave with an ingratiating request to inspect ("I
    have never seen a truck like that before . . . . 'Course I’m only
    31 years old."), in the presence of two eager troopers and the dog,
    throws doubt on the voluntariness of any manifestation of consent,
    but appellant has not expressly raised voluntariness of his consent
    as an issue before us.
    Nevertheless,       appellant's     contention      that    the    searches
    exceeded the scope of consent raises several concerns.                  To start
    with,     there   is   difficulty   with   the    search    of    the    "engine
    -20-
    compartment."        The court has described the troopers’ resort to a
    screwdriver and their look inside the compartment immediately after
    appellant’s affirmative answer to the "do you mind" request.                   The
    consented-to search of the engine compartment extended beyond the
    clearly delineated engine compartment to include prodding, tapping,
    banging, stepping up and crouching down, and even opening the
    Volkswagen's side panels.            Trooper Rugen justified his extended
    search by contending that he was unclear as to the precise location
    of the engine compartment.           Regardless of whether this professed
    confusion was objectively reasonable, he failed to clarify what
    area     he   had    been   given    consent   to   search.      Under        these
    circumstances, at a minimum, "the scope of [appellant's] consent
    was ambiguous – an ambiguity that could have been but was not
    clarified by further inquiry."          United States v. Infante-Ruiz, 
    13 F.3d 498
    , 505 (1st Cir. 1994).
    Within two minutes of appellant’s consent to search "the
    engine    compartment,"      Rugen    asked    if   he   could   look    in    the
    Volkswagen’s cab.       As the court reports, the answer was inaudible.
    The court states that "the videotape suggests that Hornbecker
    consented."         I assume that this means that appellant did not
    protest.
    At this point, after playing fast and loose with the first
    limited consent, then displaying forceful determination to continue
    the job and following with another request to examine a specific
    place, should not the officers have paused to make sure that
    consent was forthcoming and unequivocal?             I fear that the court's
    -21-
    opinion will serve to encourage scenarios of familiarity leading to
    limited consent, followed by a sequence of escalating intrusions
    resulting in an abandonment of any limits to the scope of a search,
    all sanitized by continuing to infer consent.
    As if all this were not enough, Rugen admitted that after
    finding nothing suspicious in the consented-to search of the cab,
    he began to move around the vehicle more.            Rugen then requested
    that appellant open the gas port, admitting at trial that he was
    not asking permission.       Appellant indicated that a screwdriver
    could be used here, too.     This viewing at last yielded something --
    the realization that neither the engine nor the gas tank occupied
    the space that in Rugen's mind, apparently, appellant had been
    questioned about.
    The search for a principled basis for decision in such a case
    as   this   is   made   complex     by     the   fact-specific      issue   of
    reasonableness underlying the Fourth Amendment.                But I find a
    benchmark   in   comparing   this   case    with   two   of   our   automobile
    investigative stop cases, relied on heavily by the government,
    United States v. Chhien, 
    266 F.3d 1
     (1st Cir. 2001), and United
    States v. Sowers, 
    136 F.3d 24
     (1st Cir. 1998).                In Chhien, the
    sequence of events began with the customary traffic violation, then
    a consensual pat-down yielding a large wad of money, leading to a
    few questions and inconsistent answers, followed by suspicious
    movements of a passenger in the car, refusal to open a clenched
    fist, and, finally, when the passenger was removed from the car,
    contraband in plain view.      Chhien, 
    266 F.3d at 4-5
    .             In Sowers,
    -22-
    there were signs of nervous behavior at the start, substantial
    discrepancies in answers to simple travel questions, a written
    consent to search, and a pat-down yielding a package of contraband.
    Sowers, 
    136 F.3d at 25-26
    .
    Those cases seem to me soundly decided, but debatable.               If
    they are at or near the line, this one is well beyond it.           This is
    a case where each discrete act of the troopers, if looked at
    through a narrow lens, may pass muster.         But how many such close
    calls may be made without tainting the final decision?                Is it
    enough to say that a straw is just a straw without worrying when
    one more straw will break the camel's back?             I am left with a
    profound feeling    that   in   this   case   the   officers    "pushed   the
    envelope" too far and that our affirming the district court could
    be interpreted as an Open Sesame to law enforcement to prolong
    Terry   stops,   require   irrelevant     information     and    documents,
    establish an atmosphere of coziness that ultimately suffocates an
    individual’s freedom to choose, ask for limited permission to
    search, and then subtly overreach its scope and interpret coerced
    acquiescence as implied consent.
    I therefore would reverse the judgment of the district court
    and order that it suppress the drugs found in the Volkswagen.
