1982 Porsche 956 – $10,120,000
In 1983, this Porsche 956 won Le Mans. That was the same year Porsche took nine of the top ten positions in the race. It was a good year for the brand. Another good year for the brand was 2015 when this one sold for $10.1 million at Gooding & Company’s auction. That was after experts valued it between $7-9 million. Porsche made 28 of these bad boys, but only 25 still exist.
