11. 1967 Chevy Corvette L88
Price: $3.85 million in 2014
If you wanted a racetrack ready ‘Vette in ’67, this ultra-rare ‘Vette was the one you wanted. In total, only 20 were ever made. GM claimed that it only produced 430 horsepower but when Barrett-Jackson performed a dyno-test on the ’67 L88, she churned out 560 hp. No radio or heater in these babies…and it came in one color, red.
