An ultra-rare 1937 Delahaye 135 Competition Court Torpedo Roadster topped RM Auctions' Amelia IslandConcours d'Elegance last Saturday, fetching $6.6 million with its seductive curves, blue-and-cream body, and siren-red leather seats.

The company scored its best-ever results, it said in a statement, raking in a total of nearly $36 million over 97% of all lots sold, representing a 34% increase over 2013's sale results.

The Delahaye, built by Figoni et Falaschi and offered as the jewel of Malcolm Pray's 16-vehicle collection and known as “Malcolm’s French Mistress”, was prized for being the only surviving example with its Géo Ham body tag. Additional top lots from the Pray Collection include the 1958 BMW 507 Series II Roadster, which also smashed records with its winning $2.4 million bid; a 1961 Ferrari 250 GT Series Cabriolet, which sold for $1.8 million; and a 1957 Mercedes-Benz 300 SL Roadster, originally owned by Hollywood actress Natalie Wood, which brought $1.8 million.

“We could not be happier with the results of our 2014 Amelia Island sale,” says Gord Duff, car specialist at RM Auctions. “Despite the weather, our fantastic selection of cars and stylish presentation were showered with rave reviews from our international clientele.”

Other top lots at Amelia Island include a 1934 Duesenberg Model SJ Convertible Sedan by LeBaron that brought $1.57 million, and a 1965 Shelby 289 Cobra that sold for $990,000.

Meanwhile, RM was particularly excited about selling an original 1972 Ferrari 365 GTB/4 Daytona Berlinetta for $781,000, and a show-condition and rally-ready 1939 Aston Martin 15/98 Short Chassis Open Sports that fetched $616,000.
