Corrected entry: In the scene where Stifler, Finch, Cadence and Kevin are preparing to head north for the wedding, Finch gets in the back seat of Kevin's car to be with Cadence. She then leaves to ride with Stifler. It shows Cadence getting into Stifler's car, and we still see Finch in the back seat of Kevin's. The very next shot is Kevin driving away, and Finch has magically moved to the front seat.

Correction: There is an obvious time difference. In the time that it takes Stifler to get in the car and start it up, Finch could climb into the front seat.
