The F40 is one of the finest road cars to drive out of Maranello’s famous gates, a twin turbocharged V8 race car for the road created to mark Ferrari’s 40th birthday. Auctioneers RM Sotheby's say this example is "potentially the most radical road-going F40 ever created". Extensive competition history and expert upgrades underline their point. If you're considering an F40, this may well be your car. You’ll certainly never see another like it.

This F40 is presented in stealth Grigio Nardo, because the Ferrari's current owner wanted his F40 to recall Scuderia Ferrari sports racers of the 1960s. It would have left the factory, as the other 1,314 F40s did, sporting a smart coat of Rosso Corsa, Italy's racing colour. As part of a complete overhaul Zanasi Group of Maranello also installed electric blue fabric racing seats and applied the correct Ferrari shields to each front wing.

With design by Pininfarina, the F40 was the last model that Enzo Ferrari personally signed off. A standard F40 can reach 200 mph. Competition modifications by race specialists Michelotto allow this example to produce up to 1,000 bhp, the power of a Bugatti Veyron in a lighter car. Price at RM Sotheby's is strictly on application. Recent sales suggest you'll need at least £4-million to get the F40 in your garage. Worth every penny? Just look at it.
