When Craig agrees to lend his car to Sandra and explains what kind of car it is, he tells her it's a 1970 Lime Green Super Bee with dual overhead cams. The Super Bee was never available with an engine using dual overhead camshafts. In 1970 the Plymouth Super Bee was available with three choices of engines. Base engine was the 383 Magnum, then as options there was the 440 "Six Pack" and the famed 426 "Hemi". All of these used the Overhead Valve design or "OHV" design.
In the early moments of the movie, when the car's up on it's bumper against the pole, the girl puts her keys in the door to unlock it and when the door opens, the bell goes off, to alert that the keys are in the ignition, or that the lights are on. Neither is true.
