MARANELLO, Italy - Certain cars that, because of their rarity and/or the role they’ve played in automotive history, simply must be preserved. As 2012 is the 60th anniversary of the Ferrari 250 GT the Ferrari Museum has organised a series of exhibitions of the most famous cars to bear the 250 badge.These are the road-going and racing models which, from 1952-63, were powered by the 3000cc V12 designed by Gioachino Colombo. Image gallery.Visitors can admire two specifically fascinating examples: the Ferrari 250 GT Berlinetta SWB (competition version) with which the great Stirling Moss won four races in 1961 (Silverstone, Brands Hatch, Goodwood, Nassau) and the so-called Breadvan.UNTIMELY ENDThe 250 GT SWB, finished in the classic blue-and-white livery of Scot Rob Walker, was recently restored by the Ferrari Classiche department. It was originally built as part of a chapter in motor racing history that, sadly, went unwritten: Enzo Ferrari had reached an agreement to supply the highly efficient British team with an F1 single-seater for Moss but just before the project was to debut Moss was in the terrible accident in a Lotus at Goodwood, England, that ended his racing career.That was the untimely end to a budding relationship between the two teams that might well have changed motorsport history and given Moss the World title he was chasing.The Breadvan’s story is no less interesting... It's a berlinetta extreme in terms of its form and technical content commissioned by Count Volpi di Misurata to compete against the 250 GTO. The car, developed by Piero Drogo and Giotto Bizzarrini on the same running gear as the 250 SWB, looked more like a racing van than a racing car; its square shape was the result of experimental aerodynamic styling.The result was that it was quickly dubbed 'The Breadvan' by the British. Fast, but not blessed by fortune, it raced several times, including at Le Mans. However Enzo Ferrari was opposed to it because he would brook no rival for his 250 GTO.ICONIC EXAMPLEIn 2010 Ferrari awarded The Breadvan an 'Attestation for Vehicles of Historic Interest', a document issued for Ferraris which, although tnot complying with the strict Ferrari Authenticity Certification criteria, are deemed to be of historic interest because of their competition and/or recognised international show history.The Breadvan is probably the most iconic example of this kind of car.The Ferrari Museum in Maranello is open daily from 9.30am to 7pm and houses many high-profile historic cars in addition to Ferrari's most successful F1 cars and contemporary road-going GT's.
