At the end of the movie when Jonathan loses it and starts smashing into Kenny's red '55 Chevy, they take off down the street ramming each others' car. Kenny crashes into the passenger side of Jonathans' Studebaker not once, but twice. Yet when Jonathan wheels back to the curb to talk to the ugly-duckling-turned-swan-girl, the car has no side damage at all.
This movie was supposed to be set around 1956. In the beginning of the film, Gene and Jonathan are outside the school and Gene is trying to teach Jonathan how to be "cool." Right after that, they go into the school and a tune by Chuck Berry called "School Days" begins to play. That tune by Berry was not released until 1964!
In the final scenes, the director used at least 2 Studebakers. A '50 and a '51. Both the same color and body style. However, it is obvious if you look at the noses of the 2 that they are different. This is probably the reason one should have been mashed more than it showed. It was a different car.
PLUS all '51 Studebaker model cars have a one-piece windshield, so they stuck a strip of chrome down the middle to make it look like a '50--which has a 2-piece.
