From 1971, the AMC AMX was no longer available as a two-seater. It evolved into a premium high-performance edition of the Javelin, which was a pony car that was built by the American Motors Corporation between 1967 and 1974.
The new Javelin-AMX was advertised it as “the closest thing you can buy to a Trans-Am champion.” The new 1971 design incorporated an integral roof spoiler and sculpted fender bulges. Engines options included the 245 hp 360 cu in (5.9 L) V8 or the 335 hp 401 cu in (6.6 L) V8.
During the 1972 and 1973 model years 4,152 Javelins were produced with optional interior design by fashion designer Pierre Cardin. The design had multi-colored pleated stripes in red, plum, white, and silver on a black background. Six multi-colored stripes, in a nylon fabric with a stain-resistant silicone finish, ran from the front seats, up the doors, onto the headliner, and down to the rear seats. Cardin's crest appeared on the front fenders.
