1) the movie makers like making viewers cringe.
2) the state of california allows movie companies to sell pollution
credits for old cars they destroy.
3) most often the car that is destroyed is essentially a parts car
dressed up. (still a waste)
Thus spake Brent :
I heard an interview with one of the actors in a recent "cop buddy
movie" where he said they shot it on such a cheap budget that when
they trashed a car on one side, the turned it around for another
scene. And god help you if you screwed up when they did a crash.
The actor said, at one point, "we were so cheap I did some of my own
stunts. Like that scene where I get real drunk? I had to do my own
drinking and get my own hangover!"
The studios have a number of sources for cars, trucks, etc. Those cars
can be modified to look like whatever they need. When they get
mangled, they go back to the shop to be rebuild again and again and
again. To film a movie or TV show, there are often quite a number of
"copies" used. "Gone In 60 Seconds" was a prime example. Several cars
were automatics and a couple were manual.
In show/movies where vehicles are not damages, the studios contract
with owners to use those vehicles (the do the same with homes, boats,
planes, etc). Most of the vehicles used in period movies (like the
1930s, etc) come from private owners.
Movie cars are BIG business.

Dukes of Hazzard TV show destroyed 169 Dodge Chargers. But back then, you
could buy them for about $3000...with a 383. Flash forward. Nash Bridges
couldn't afford to risk real Hemi convertible 'Cuda's so they used clones.
Thus spake Rich :
Miami Vice had him driving a Daytona knockoff (body kit on an early
80s Vette). Ferrari offered up a red head if they would dump the
"Daytoa". Which they did, rather dramatically.
Plenty of glas body parts on there. Remember Ferris Buhler? About a
year after the movie came out one of the "GTO's" was offered for sale
in either C&D or R&T.
