Steve McQueen's 'Le Mans'!
Though it's not so much a movie as a series of great shots of beautiful Le Mans cars. There is a plot, but it's not worth too much, just great for atmosphere; the sights and sounds of Le Mans captured on film.
There is "Speedway", from 1929 and has footage from the 1929 Indy 500. It is a silent movie, but has cameo appearances from racing drivers of the day.
TT3D: Closer to the Edge, is a 3D film of the Isle of man TT, absolutely insane and a must-have.
Spinout, an Elvis movie from 1966. Don't laugh, some of the cars used in the film are absolute classics. If you know and appreciate cars from that era, I highly recommend it.
The Cannonball Run nice cars, great comedy.
Stroker Ace, another amusing Burt Reynolds movie, but not worth the price of admission.
