In the scene where Blaine and Duane are in their car and the monster truck is jumping the ramp over the other cars and coming at them, they show a first scene where the monster truck is approaching the ramp and the first car after the ramp is an old Lincoln Continental, then there is what looks to be a K-car and then a Ford Tempo after that. Then, in the scene where the monster truck actually jumps the ramp, the first car after the ramp has changed from the Lincoln to an Oldsmobile Cutlass Cierra and the cars after that have changed to I think an old Nissan and an old Toyota Celica.
