That and it was 'just a movie'. You could go cross country in a quasi-gasser in a movie, but a possessed '58 Fury might be chasing you all the way.
I might be able to jump into this one. What kind of vehicle? Don't know. But it would have to be something with decent power, good handling, and above all reliable for all the action it's about to see. Possibly something that was successful in the NASCAR circuit of the era, or maybe a specially prepped sports car.
