On May 1st RM Auctions will inaugurate a new annual sale in Monaco headlined by a rare Ferrari expected to fetch up to $3.5 million. The Sporting Classics of Monaco event will be held at the Grimaldi Forum during the same weekend as the 7th Grand Prix Historique de Monaco. 80 of the world's finest motor cars will be on offer, headlined by a stunning 1962 Ferrari 400 Superamerica Cabriolet Pininfarina (above). One of only six short wheelbase examples bodied by Pininfarina, the Ferrari, chassis no. 3309SA was the last example built, and displayed as a factory show car at the Geneva and New York Auto Shows in 1962. The car, which recently underwent a no-expense spared, nut and bolt restoration by top tier marque specialists, won an award at this year's famed Pebble Beach Concours d'Elegance. Widely regarded as more exclusive, powerful and luxurious than the SWB California Spider, its offering is set to garner significant attention from collectors around the world.
