The Choppers hook up a tow line to a car they find abandoned on the side of the road, a light-colored 1959 Buick two-door convertible, and tow it to a side road in order to strip it. However, when they come to the end of the road and unhook the car, it has turned into a dark-colored late-1940s four-door sedan. The same Buick again turns up near the end of the picture as the last car they try to strip.
As the Choppers' truck is driving down the highway, a police car - a 1957 Plymouth - pulls up behind them and turns on its siren to have them pull over. However, when the car pulls alongside of the truck and forces it to the side of the road, it has turned into a 1959 Chevy.
When the gang is terrorizing Norman and his girlfriend in their car at the drive-in, Snooper remarks that Moon hubcaps - a lightweight hubcap that covers the entire face of the rim - dent easily, and a close-up shows someone's foot kicking several dents in a Moon cap. However, when Norman's car finally backs up a few seconds later and leaves the drive-in, there are no Moon hubcaps on it, only small round caps that cover just the hub of the wheel.
