Defendant-appellant Gerry Carlyle McSween (McSween) appeals his conviction on a conditional plea of guilty to possession with intent to distribute crack cocaine after the district court denied his motion to suppress the drugs recovered from under the hood of his car. We affirm.
Facts and Proceedings Below
On February 26, 1994, Texas Department of Public Safety Officers Ralph Billings (Billings) and Larry Price (Price) stopped McSween for driving 87 mph in a 65-mph zone. As Price conducted a computer check, Billings began to write a speeding ticket. Noticing a cellular phone and radar detector in the car’s interior, Billings asked McSween if he could look in the car and trunk. McSween consented, and Billings opened the hatchback. McSween then helped Billings remove, with screwdrivers, the hatchback’s interior panels.
Meanwhile, Price had completed his computer check, which indicated that McSween had four prior arrests on narcotics charges. After informing Billings of McSween’s record, Price moved to the car’s passenger side and asked McSween if he had any objection to his searching the vehicle. McSween consented. While searching the passenger area, Price noticed the smell of burnt marihuana, which he at first suspected was emanating from the ashtray. Finding no drugs in the ashtray or passenger area, Price opened the hood and noticed a red rag sticking out of a hole in the car’s fire wall. Price removed the rag and saw in the hole what appeared to be a brown plastic bag. Fingering the bag, Price concluded that it felt like it contained a *686 “small bale” of marihuana. Price then replaced the rag and arrested McSween. After the car was impounded, troopers inspected the hole and found a bag of marihuana and a shoulder sling of crack cocaine.
A grand jury indictment returned March 8, 1994, charged McSween with possession with intent to distribute 50 or more grams of crack cocaine in violation of 21 U.S.C. § 841(a)(1). McSween moved to suppress the evidence seized from his car, arguing that the officers lacked probable cause and exceeded the scope of his consent. After a suppression hearing, at which McSween did not testify, the district court denied the motion, concluding that the initial stop was justified, that McSween’s consent to search was voluntary and the search within its scope, and that the subsequent arrest was supported by probable cause. Thereafter, on May 19,1994, McSween entered a conditional plea of guilty, preserving the suppression issue for appeal. Fed.R.Crim.P. 11(a)(2). The district court sentenced McSween to 136 months in prison and 5 years of supervised release. McSween now appeals.
Discussion
McSween argues that the district court erred in denying his motion to suppress because there was neither probable cause nor consent to search under the hood of his vehicle, nor probable cause to arrest him. Viewing the evidence in the light most favorable to the government, the prevailing party,
United States v. Maldonado,
I. Probable Cause for the Search
It is well settled that warrantless searches of automobiles are permitted by the Fourth Amendment if the officers have probable cause to believe that the vehicle contains contraband or other evidence of a crime.
See United States v. Ross,
It is undisputed that Price had MeSween’s consent to search inside the passenger compartment of McSween’s new rental car. At the suppression hearing, Price testified that, when he entered the car, he noticed “the odor of what I thought was burned marijuana.” Price testified that he based this conclusion on his twenty-two years of experience and training in the detection of marihuana by its odor. He further testified that the smell appeared to be coming from the ashtray, but he discovered nothing there or anywhere else inside the vehicle’s passenger compartment. He then decided to look under the hood. At this point, Price had smelled but not located marihuana and knew of McSween’s four prior arrests on narcotics charges.

Together these facts, viewed in light of Price’s experience, justify a finding of probable cause to search the entire vehicle. Indeed, the smell of marihuana alone may be ground enough for a finding of probable cause, as this Court has held many times.
See, e.g., United States v. Reed,
McSween contends that, even if the odor of marihuana gave Price probable cause to search, the search should have been limited to the passenger area, where Price detected the smell. We disagree. It is well settled that, in a case such as this, the detection of the odor of marihuana justifies “a search of the entire vehicle.”
Reed,
II. Consent for the Search
In the alternative, we agree with the district court that the search under the hood was within the scope of McSween’s consent. Under the Fourth Amendment, “[t]he standard for measuring the scope of a suspect’s consent ... is that of ‘objective’ reasonableness- — what would the typical reasonable person have understood by the exchange between the officer and the suspect?”
Florida v. Jimeno,
Viewing the testimony at the suppression hearing in the light most favorable to the government, we conclude that Price asked
*688
McSween for general permission to search his vehicle. Price testified, “I asked ... if ... [McSween] had any objection of [sic] me searching his vehicle.” Asked then if that was “more or less the language ... used,” Price responded, “Yes.” Even if Price actually asked to “look in” McSween’s vehicle, we would still conclude that in these circumstances Price effectively asked for a general consent to search. In
United States v. Crain,
The question, then, is whether it was reasonable to interpret McSween’s general oral consent to search the car as authority to search under the hood. Although-the “scope of a search is generally defined by its expressed object,”
Jimeno,
In such circumstances, a failure to object to the breadth of the search is properly considered “an indication that the search was within the scope of the initial consent.”
United States v. Cannon,
*689
In
United States v. Sierra-Hernandez,
III. Probable Cause for the Arrest and Subsequent Search
McSween next argues that the officers lacked probable cause to arrest him, impound the vehicle, and conduct a further search. McSween claims that the cocaine should be suppressed “because the only thing that was determined during the ... search on the highway was that there was an object wrapped in plastic in the hole under the hood.” An officer has probable cause for an arrest when “the facts and circumstances within the knowledge of the arresting officer are sufficient to cause a person of reasonable caution to believe that an offense has been or is being committed.”
United States v. Walker,
Finally, we must reject McSween’s suggestion that, even if the arrest and initial search were supported by probable cause, the second search of the ear at the sheriffs office, where the cocaine was discovered, required a warrant. If probable cause justified a warrantless search on the roadside, it likewise justified one at the station after the car was impounded.

Ross,
Conclusion
For the foregoing reasons, the judgment of the district court is
AFFIRMED.
Notes
. Also, though of at most entirely minimal relevance, McSween had a cellular phone and radar detector.
.This is simply not a case such as
United States
v.
Chadwick,
“[l]t was the luggage being transported by respondent at the time of the arrest, not the automobile in which it was being carried, that was the suspected locus of the contraband. The relationship between the automobile and the contraband was purely coincidental, as in Chadwick," Ross,456 U.S. at 813 ,102 S.Ct. at 2167 (quoting Sanders,442 U.S. at 765 ,99 S.Ct. at 2594 (Burger, C.J., concurring)).
In
Ross,
the Supreme Court clearly limited these two cases to their facts,
Ross,
. Although the district court rested, the constitutionality of the warrantless search on McSween's consent, we can affirm the lower court’s decision on any grounds supported by the record.
Bramblett v. Commissioner of Internal Revenue,
. McSween does not contest the district court’s finding that the consent in this case was voluntary. Nor does McSween challenge any other factual findings made by the district court. The only remaining question, the scope of consent, is considered a question of law in this Circuit and is, accordingly, reviewed
de novo. United States v. Rich,
. McSween did not testify at the suppression hearing. Defense counsel, however, suggested that it may have been difficult for McSween to object because of the speed and obscurity of the search. The district court did not clearly err in finding this suggestion incredible, especially as counsel’s claim is pure hypothesis. The only evidence at the hearing related to this claim supports the district court's finding. Billings, who was standing with McSween at the rear of the vehicle during Price’s search, testified that he was aware Price had opened the hood and was searching that area. In any event, as we stated in
Rich,
”[W]e are unwilling to read
Jimeno
to hold ... that enforcement officials must conduct all searches in plain view of the suspect, and in a maimer slowly enough that he may withdraw or delimit his consent at any time during the search.”
Rich,
. This case is not one in which the officers interpret a general consent to search the vehicle as authority to inflict damage on the vehicle or its contents.
United States v. Strickland,
. McSween attempts to distinguish this case by arguing that here there were circumstances that would make a reasonable officer realize the “initial consent” was limited. As pointed out earlier, however, the consent given in this case authorized a general search of the car.
. When asked whether he thought there was anything unusual about a rag sticking out of a fire wall, Price testified, "A brand-new vehicle like that, a rental car, it was unusual that you would see a rag stuffed in behind there, I felt it was.”
