250 GTO is unquestionably one of the most famous cars ever built. Designed to compete in GT racing, it's powered by a 3.0-liter V12 and mated to a five-speed manual. Built from 1962 until 1964, only 39 cars were built. With a price of $18,000 each, potential buyers had to be personally approved by Enzo Ferrari himself. Continuously at the top of many lists as one of the best sports cars of all time, it's rare to even see one in a lifetime.
