 According to Keith Gordon on the DVD Commentary, he kept having  trouble with Christines ignition. The 1958 Plymouth Fury has a  "push button" starter meaning you turn the key and push a button to  get the car to start (The button can be seen in some shots located  near the steering column but is never seen being pushed in the  film). He says that it would routinely take several tries to get the  engine to turn over. In a few instances, filming would be delayed so  that a technician could repair the starter and even then hed still  have trouble with it.
