They must have gone through several. I’m guessing they had 3 cars, from what I remember. I saw it at the drive-in (where else?) when it came out.
We never knew how rare those cars from those days would become. Or we would have kept many of them.
They had 3 or 4 cars for “Vanishing Point” - which was great. From what I read, they had to keep transferring parts from one car to another.
The final wreck into the dozers was a camaro. It’s rather obvious from the footage it ain’t a Challenger.
Some of my favorite songs from that movie:
