OPINION

Carrizoza-Gaxiola was charged with transporting a stolen vehicle in foreign commerce in violation of 18 U.S.C. § 2312 . Before trial, he moved to suppress evidence gained from an allegedly illegal stop. The district court granted his motion and the government appeals. We affirm.

Carrizoza-Gaxiola was observed and then stopped by a team of federal and state law enforcement officers outside Nogales, Arizona. The purpose of this joint effort was to intercept vehicles stolen in the Phoenix and Tucson areas and transported into Mexico at Nogales. The stop was made about 13 miles north of Nogales on Interstate 19, a major highway between Nogales and Tucson. Only vehicles that are traveling towards Mexico and that meet a specified profile are stopped. The profile includes types of vehicles that are commonly stolen in Phoenix and Tucson and then transported to Mexico. Among these are Ford LTD’s of the model years 1970-74. If a vehicle meets the profile and if the officers suspect that it might be stolen, an officer in a marked Arizona Highway Patrol car drives onto the highway and stops the vehicle for a driver’s license and automobile registration check. The officer then calls in the vehicle’s identification number to a central information center to determine if it has been stolen. If so, the driver is arrested and the vehicle impounded. Vehicles that do not meet the profile pass through the area without interference.

In this case, Carrizoza-Gaxiola was driving a late-model Ford LTD when he entered the surveillance area. He was stopped because he appeared to be Mexican, because the ear he drove appeared to be brand-new and because it had Mexican license plates. A check of the car’s identification number revealed that it was stolen.

The government argues that the stop was authorized by Arizona law, specifically the following statutes:

Ariz.Rev.Stat. § 28-305(D).

Ariz.Rev.Stat. § 28-423.

Some doubt surrounds the question whether these statutes authorize stops to check license and registration without founded suspicion. The Arizona Supreme Court has not addressed the issue and only one division of the Arizona Court of Appeals has so held. State v. Ream, 19 Ariz.App. 131 , 505 P.2d 569, 571-72 (1st Div. 1973); State ex rel. Berger v. Cantor, 13 Ariz.App. 555 , 479 P.2d 432, 434-35 (1st Div. 1970). Another division has expressly declined to follow this holding where, as here, the purpose of the stop is to determine whether a vehicle is stolen. State v. Taras, 19 Ariz. App. 7 , 504 P.2d 548 , 551 & n. 1 (2d Div. 1972) (dictum). However, we need not predict how the Arizona courts will resolve this question. The stop must comply with the Fourth Amendment.

The government advances two arguments for the constitutionality of the stop. First, the government argues that our decision in Lipton v. United States, 348 F.2d 591 (9th Cir. 1965), permits stops without founded suspicion to check drivers’ licenses and vehicle registrations. Assuming the vitality of that decision subsequent to Terry v. Ohio, 392 U.S. 1 , 88 S.Ct. 1868 , 20 L.Ed.2d 889 (1968), the rationale of Lipton is that laws requiring possession of drivers’ licenses while driving could not otherwise be effectively enforced. Id. at 593 . We have limited Lipton to that rationale; it permits stops without founded suspicion only to enforce laws susceptible of no other means of effective enforcement. United States v. Bowen, 500 F.2d 960, 964-65 (9th Cir.) (en banc); see id. at 972 n. 9, 973-74 (Wallace, J., dissenting), aff’d on separate issue, 422 U.S. 916 , 95 S.Ct. 2569 , 45 L.Ed.2d 641 (1975). The government concedes that the purpose of this law enforcement effort was to detect stolen vehicles, not to check for compliance with licensing and registration requirements. The government has argued neither in this court, nor in the district court, that car thieves cannot be effectively apprehended by less obtrusive means.

The government’s remaining argument is that the officers possessed founded suspicion to stop Carrizoza-Gaxiola. The facts known to the officers were: (1) a man appearing to be Mexican (2) was driving towards Nogales on a highway from Tucson (3) in a new. appearing late-model Ford LTD (4) with Sonora, Mexico license plates; in addition, (5) each week some, but less than 30, late-model Ford LTD’s are stolen in the Tucson and Phoenix areas and remained unrecovered, and (6) some of those cars turn up in Mexico.

Although this information provides grounds for believing that some of the late-model Ford LTD’s traveling towards Nogales on Interstate 19 are stolen, it does not provide any means for determining which ones. Founded suspicion requires some reasonable ground for singling out the person stopped as one who was involved or is about to be involved in criminal activity. United States v. Torres-Urena, 513 F.2d 540, 542 (9th Cir. 1975); United States v. Ward, 488 F.2d 162, 169-70 (9th Cir. 1973) (en banc). Driving a car as common as a Ford LTD is not suspicious nor is driving it towards Nogales. That the driver appeared to be Mexican and that the car had Mexican license plates add nothing beyond residence in the country to which some stolen vehicles have been transported. Mexicans commonly drive into this country and then, not surprisingly, drive back.

Affirmed.
