For the Chevrolet Caprice, three different models have been used: A 1981 Caprice Classic for the driving scenes, a 1979 for the scenes involving special tricks, and a 1977 one for the final destruction of the car.
When it crashes in the first chase, Ben's Mercedes gets heavily damaged, and it loses its Mercedes-star. In the following scenes, the car has only some minor dents, and the Mercedes-sign is still there.
When Quinn steals the police-Porsche, Semir's BMW can be seen parked next to it. However, Semir and Ben receive a message that Quinn escaped in the next scene, while driving the BMW in a completely different location.
