A 52-year-old Ferrari is now the most expensive car ever sold at auction. The 1962 Ferrari 250 GTO was sold by Bonhams Thursday for 34-point-65 million-dollars. It broke the previous record held by a Mercedes-Benz racer that sold for more than 31-million dollars last summer. Ferrari GTOs are among the rarest cars in the world. Less than 40 of them were made.
