AMC Spirit AMX
The AMC Spirit AMX secures its place among the worst muscle cars due to a combination of lackluster performance and uninspiring design. Introduced in the late ’70s, the Spirit AMX aimed to capture the spirit of a muscle car but fell short. Its modest power and conservative styling failed to resonate with muscle car enthusiasts, marking it as a forgettable entry in the world of muscle cars. The Spirit AMX struggled to embody the high-performance legacy of its predecessors.
