As far as celebrity endorsements go, Steve McQueen’s is one of the best sorts you can get. One lucky Ferrari collector has that on a Ferrari 275 GTB4. The car used to belong to McQeen, and better than that, he took delivery of the car when he was on the set filming Bullitt in San Fransisco. Quite a special car this, which is why the owner went through the hassle of bringing the car to Ferrari Classiche for the company’s authenticity certification process, and restoration to the original condition.

A previous owner of this magnificent 275 had converted it to a Spider. So the first order of business was reproducing the roof and buttresses with hand-beaten steel panels. In order to be authenticated every classic Ferrari must has exactly the same specifications as when it left the factory.

Classic Ferrari’s are solid investments, for those who are in the game for the money and not the love of the car. Recently a Ferrari 250 GTO originally built for Sir Stirling Moss was sold privately to a customer for the staggering sum of $35 million.

Thanks to this increasing interest in Classic Ferraris, the business is booming for the company’s classic section. Set up in 2006, Ferrari Classiche has to date processed over 3,300 certification requests using the company’s exhaustive archive records and original designs.
