Are 1971 mustang fastback and mach 1 the same car?
No, the 1971 Mustang Fastback and Mach 1 are not the same car, though they share a basic body style. The Mach 1 was a *higher-performance option package* for the Mustang Fastback. This means a Mach 1 was always a Fastback, but a Fastback was not automatically a Mach 1. The Mach 1 had distinct performance features and styling cues not found on standard Fastbacks.
