The Ford Mustang Mach 1 featured in the James Bond film"Diamonds are Forever".
The Ford Mustang Mach 1 is a performance-version of the regular Mustang muscle car, built by American manufacturer Ford. While the first generation covered the 1969 and 1970 model years, the one used by James Bond and Tiffany Case is a 1971 model, making it brand new at the time of the filming. The car was provided by Ford.
The Mustang Mach 1 is first driven by Tiffany, when Bond follows Prof. Metz into the Nevada deserts surrounding Las Vegas. After a security breach at Willard Whyte Tectronics, the car is wanted by law enforcement agency.
Later that day, Bond has to evade capture by former Las Vegas Police Department forces, resulting in a car chase through Las Vegas. Bond manages to lose the cops by driving on two wheels through a narrow alley.
