These configurations were made to simply resemble the look and equipment of both cars as closely as possible with the in-game parts on hand. Obviously the Barstow will never be an exact replica of either of these cars. One looks similar to the Ford Mustang that was driven by Steve McQueen while the other looks similar to the Dodge Charger that was driven by the famous stunt driver Bill Hickman. This mod contains two configurations for the Barstow to resemble the two cars involved in the movie's chase sequence. The film is famous for its iconic car chase through the hills of San Francisco. Ever seen the movie Bullitt? If you haven't you should check it out or at least watch the chase scene online.
