John Surtees is a racing legend, having won multiple motorcycle World Championships and claiming the F1 driver's title for Ferrari in 1964. Fresh off winning the 500cc title with MV Agusta in 1956, Surtees noticed a BMW 507 roadster at Germany's Hockenheim circuit undergoing testing. Surtees was smitten and purchased one for himself, going half in with Count Agusta to buy the car. For the next 60 years, the car was driven regularly by Surtees, remaining in his possession until his death in March of 2017. Offered for auction by his estate, this one-owner 507 has provenance to spare.
