 CONT: Toward the beginning of the movie, Brian is pulled over by an  unmarked black police car, a 1992 Ford Crown Victoria. When the stop  is first being made, the Crown Victoria is a modified one that does  not have a front grille with a blue Ford Oval on it. As Paul gets  out of his car, the Crown Victoria is an unmodified one, with the  grille and Ford oval on the front. So between shots, the police car  changes.
