yes it is
how did you do the search to not find it?

Yeah, there's 153 Ford Pinto's to be exact.

oops
I found the "Pinto list" under Ford !.
Top secret was not on the list of Movies...so I get one point at least.

Here is one to start the Pinto list. There is a red one in the movie Top Secret. The gag is that a small tap on the bumper explodes the car to the detriment of the mock German soldiers (bad guys) who are chasing it.

Also please add movie "Moonshine Highway"
has multiple old 1950s cars including a chase scene with a 1949 Mercury.
