Near the end of Training Day, after Jake and Alonzo have fought on the roof of the apartment building but before Jake shoots Alonzo, Alonzo is backing is car up to leave when Jake drops from the roof on to the hood of Alonzo's car. In the ensuing scene, Alonzo rams both the front and rear of his car into other cars in an attempt to rid himself of Jake (still on the hood.) The car is clearly trashed, yet at the beginning of the next sequence, when Alonzo is driving down the street on his way to meet the Russians, the front end of his car is completely untouched (and the rear looks that way as well.)
