Corrected entry: When Kurt goes inside the food store he leaves the hood of his engine open. A few minutes later, when the car breaks down, he re-connects something under the car and it works. Later in the movie, one of the bad guys say "He was an idiot for leaving the hood open", but they never touched the engine, did they?
Corrected entry: When Russell is kidnapped and is in the trunk of the Trans Am talking to the kidnappers, on the shots where they show the kidnappers from his point of view you can see a distinct curvature at the end of the trunk lid. Trans Ams of that era had flat trunk lids, that was obviously a trunk lid of a different car.
Corrected entry: Near the start of the film Kurt Russell gets a little worried and speeds away from a garage after seeing someone he almost hit earlier. After a few minutes the Jeep breaks down. Kurt finds out after a while that some wires have come undone, he puts them back together and the Jeep starts. Later in the movie the guy that he almost hit told him that he undid the wires. How did the Jeep run for so long before it broke down?
