A rare 1967 Ferrari 275 GTB/4S NART Spider sold on Aug. 17, fetching $27.5 million -- the highest price paid at auction for the Italian car maker anywhere in the world and the most for any car bought at a U.S. public sale.
Estimated to sell between $14 million and $17 million, the Ferrari had been entered by family of the late North Carolina businessman Eddie Smith Sr., the car's one and only owner.
The price, which included fees, was the second-highest for any car at a public sale after the $29.5 million paid for a 1954 Mercedes-Benz W196R that Juan Manuel Fangio drove to two Grand Prix victories, sold by Bonhams in July.
