Astonishingly, RM Sotheby’s had expected the Bugatti to attract even greater interest, with an initial estimate of $8.5m. The auction house achieved $70m in sales over last weekend’s Amelia Island auction, bolstered by the sale of an Aston Martin Short-Chassis Volante at $2,145,000 and Mike Tyson’s Ferrari F50 at $2,640,000.
