1969 AMC AMX/3

Arguably the sexiest vehicle on this list, the AMC AMX/3 was created after AMC executives stared at the De Tomaso Pantera for hours and tried their damnedest to emulate those achingly perfect lines. To be fair, AMC succeeded; the AMX/3 is stunning. With its engineering spearheaded by Giotto Bizzarrini, AMC’s AMX/3 was also mid-engined, featuring a 6.4-liter V-8 nestled behind the occupants’ heads.

The car is noteworthy for two million reasons, which is the amount of dollars AMC dumped into development before pulling the plug. (Adjusted for inflation, that’s about $15 million, today.) Only six AMX/3s exist, edging the valuation of each well above $750,000.
