I'd say"American Graffiti" is a yes as the movie revolved around the 60's cruising and street racing culture. Harrison Ford drove the bad ass double-nickle Chevy.
A few others for consideration:
"Two Lane Blacktop" - 55 Chevy and 71 GTO Judge race across the country for pinks. Starred Warren Oates as "GTO" with James Taylor and Dennis Wilson (I believe) driving the 55.

"The Last Ride" - Campy movie featuring 69 GTO Judge and an 04 GTO with Dennis Hopper. This movie was really a thinly veiled Pontiac marketing tool for the new generation GTO.
