Ford Mustang Mach 1

In the 1971 movie Diamonds Are Forever, James Bond (Sean Connery) and Tiffany Case (Jill St. John) drive around Las Vegas in a red 1971 Ford Mustang Mach 1.
Mach 1 is a special performance option package for the Ford Mustang 'Sportsroof' (or 'Fastback').
The red Mustang is first seen at the McAllen International Airport in Las Vegas, when Tiffany Case and Bond follow the Willard Whyte van driven by Bert Saxby, one of Ernst Stavro Blofeld's leading henchmen. Tiffany Case later picks up Bond at Whyte's research laboratory in the desert. This time Bond takes the wheel and they end up in a thrilling car chase with the police on Fremont Street in Las Vegas.
Bond gets away by putting the Mustang on two wheels and escape through a very narrow alley. In one of the more famous movie mistakes, the car comes out riding on the other two wheels. A shot was added showing Bond and Case in the car that changes to the other side, without explanation of how that would have happened.
The Mach 1 in the film has a red exterior and black and red leather interior. The license plate of the car in the movie reads CA52H6.
This is not the first Ford Mustang seen in a James Bond film: Tilly Masterson drives a white Ford Mustang convertible in the movie Goldfinger (1964) and Fiona Volpe drives a blue Ford Mustang convertible in Thunderball (1965).
