Mark Donohue built his reputation on spotting a bad race car in seconds, and by his own account, AMC’s first Trans-Am Javelin nearly failed that test completely. This 1970 AMC Javelin SST Trans Am, one of just 100 street versions built to homologate the race car for SCCA competition, carries the 325-horsepower 390 V8 and 4-speed manual that made it road-legal. Its story includes an owner who kept it for thirty years and a debate over what SST even stands for. Watch to see how a car once dismissed as a mess helped AMC finish second in points.
