Jack Warden is brilliant in a double role as two feuding brothers, Luke and Roy L. Fuchs, who own competing car lots and are trying to drive each other out of business.

Rudy Russo, played with oily gusto by Kurt Russell, is Luke's ace salesman, a charming and conniving cheat and liar who is merely in training for his true ambition—politics.

Co-written by "the two Bobs"—Robert Zemeckis and Bob Gale (I Wanna Hold Your Hand)—and starring an ensemble cast of comedy favorites including Gerrit Graham, Frank McRae, Joe Flaherty, David L. Lander and Michael McKean, Al Lewis, Dub Taylor, Wendie Jo Sperber, and Deborah Harmon, the film is a no-holds-barred, rude, crude and outrageous comedy about car dealers and the dupes they are desperate to send away in the previously owned automobiles of their dreams—buyer beware, all sales are final.

Used Cars is directed by Robert Zemeckis, produced by Bob Gale, and executive produced by Steven Spielberg & John Milius, a follow-up to 1941, the team's hellzapoppin' WWII comedy extravaganza from the year prior.
