The film used 13 different cars bought at auction from the California Highway Patrol to depict the retired 1974 Mount Prospect, Illinois, Dodge Monaco patrol car. The vehicles were outfitted by the studio to do particular driving chores: some were customized for speed and others for jumps, depending on the scene. For the large car chases, filmmakers purchased 60 police cars at $400 each, and most were destroyed at the completion of the filming. More than 40 stunt drivers were hired, and the crew kept a 24-hour body shop to repair cars.
