£29.5 million – While only second on this list, this 250 GTO is still the most expensive car sold at auction. It went for $38.1 million back in 2014, which puts its value at nearly £31 million in current terms and nearly 40 million in USD.

This particular car was raced by Jo Schlesser, who tragically died on his F1 debut in 1968. The Frenchman bought the car to enter privately in the 1962 Tour de France but. sold the car soon after when team mate Henri Oreiller lost his life in a fatal crash at the duo’s next race.
