<P> This is a list of the most expensive cars sold in auto auctions through the traditional bidding process, that of those that attracted headline grabbing publicity, mainly for the high price their new owners have paid . A 1962 Ferrari 250 GTO serial number 3851GT sold at Bonham's Quail Auction on August 14, 2014 for US $38 million (including buyers premium), breaking the record previously held by a 1954 Mercedes - Benz W196 R race car, sold for a record $31 million at an auction in England on July 12, 2013 . While collectible cars have been sold privately for more, this is the highest price ever paid for a car at a public auction . </P> <P> The 1904 Rolls - Royce 10 hp Two - Seater is currently listed on the Guinness World Records as the most expensive veteran car to be sold, at the price of US $7,254,290 (equivalent to $8,562,000 in 2017), on a Bonhams auction held at Olympia in London on December 3, 2007 . </P>
