Most expensive cars ever sold at auction

This was the most money ever paid for an American car at auction. This was one of three lightweight GT40s built and one of only two that still survive. Beyond its strong racing history, this GT40 was also used as a camera car for the Steve McQueen film "LeMans." The strong collectible value of Ford GT40s has rubbed off on its successor, the 2005 and 2006 Ford GT supercars which also retain surprising value.
