Auctions are great for more than just spending your family's fortune of monopoly money on the world's most spectacular cars. They're a peek into the collective car tastes of the present through the window of the past. So, we took a look back at every car that's set the world record for highest price sold at auction. These cars, and their prices, are at the same time staggering and perfect fodder for Warren Buffett's motivational poster.
Ed. Note: The most expensive car ever sold was a Ferrari 250 GTO that went for a mind-boggling $52 million, but it never went to auction.
