In the 1971 James Bond film Diamonds Are Forever, which Ford model is used by Tiffany Case?

In Diamonds Are Forever, Tiffany Case uses a Ford Mustang Mach 1.

The red Mustang is associated with Tiffany Case, a diamond smuggler who becomes Bond’s ally. The car is seen in Las Vegas, where it contributes to the film’s bright American setting and its emphasis on casinos, luxury hotels, and elaborate car chases.

The Mach 1 was a performance-oriented Mustang package introduced for the 1969 model year. It combined distinctive styling with V8-powered options and was marketed as a fastback muscle car. The film uses the car as part of the broader visual language of early-1970s American motoring.

This should not be confused with the Ford Mustang used by Bond in the narrow Las Vegas alley sequence. That car is also a Mach 1, but Bond’s driving scene is the more famous one. Tiffany’s Mustang is a separate appearance of the same model in the film.
