The mold for this film's centerpiece 1973 Corvette car is part of the collection of America's National Corvette Museum and displayed at the Corvette Americana Hall of Fame in Cooperstown, New York. The museum also screens this movie regularly.
Mark Hamill said of this movie around the time of production: "I insisted on looking different. And I'm only interested in the car, not even any girl, until Annie Potts came along. . . It's not a car movie. It's really a love story. And I'm so thrilled to be working with Annie Potts. She reminds me of Judy Holliday. She's a unique creature." Hamill years after the film first came out then said: "Corvette Summer is a great little picture and it's got sort of a title that's a misnomer because you sort of put it in one category when you first see it and you go, 'Oh gee, it's quite a nicely written, uh romantic movie.' And I enjoyed it immensely."
The Corvette car was a 1973 Chevrolet Corvette Stingray converted to right hand drive so that Mark Hamill could hang out of the curbside window looking at the ladies. The car was also painted candy apple / cherry, given superior mags, a clam-shell hood, Gabriel shocks, Merry tubes, a metal flake, side-pipes, and flames painted on the body.
Originally entitled "Stingray" until another movie with the same title was released first, probably to cash in on the advanced hype of Mark Hamill's first post-Star Wars: Episode IV - A New Hope (1977) movie role. Both flopped.
