When Colt forces a villain's car off a bridge, the bad guys are clearly driving a hard-top Mercedes. However, the car that goes off the bridge is an American made convertible. Also, the bad guys are dressed all in back, but of the bodies that fly from the falling car, one is wearing a white shirt the other a red shirt, matching the clothes that Colt and Howie were wearing, but the two of them are safely still on the bridge.
Colt describes Salem's appearance to the guy at the airport even though he'd never seen the guy, nor had any basis for knowing what Salem looks like.
