AMC AMX
The main difference between the 1968 AMC Javelin and AMC AMX was that AMX was a two-seater model, the only two-seater on the US market other than the Corvette. With a shorter wheelbase, 390 V8 engine with 360 hp, lots of go-fast options, and a reasonable price, AMC AMX was an exciting and capable muscle car. The Javelin proved to be a sales success, but the AMX was tough to sell, and people wanted more room in their muscle cars, so a two-seater AMX was obsolete.
