Although it really wasn't great for chase scenes, the Dukes of Hazzard used up a lot of cars. I talked to one of the people on the show once and he told me they averaged using 4 to 8 cars per show and then stripping whatever they could still use to put on other cars for the next show. Two of the shows people were going around here looking for anybody that had a MOPAR and would sell it or any parts they had.
I also saw a show on the History Channel about some place in New York that makes cars for the movies. They would cut them into pieces and then weld them back together and maybe use the same car in different configurations in several movies. The man that owned the place had three 1965 Shelby GT-350 Mustangs in his shop that were his. He said he didn't mind chopping up an $200K car for the movies, but if anyone even looked at one of his Mustangs they were fired.
