Forget tuning, Ferrari's special customers get their own car designed by the Italian firm.

Take one US customer. Not content to follow the lead of James Glickenhaus and his one-off P4/5 based on an Enzo, this guy has ordered three 600 GTOs.

The new cars will be based on the 612 Scaglietti, but shed 285kg in weight. New bodywork will also create 25 per cent more downforce at 125mph.

Ferrari won't reveal the name of this very special customer, but there are rumours that the buyer wants to resurrect the Ferrari North American Racing Team (NART) that was founded by Ferrari's original US importer Luigi Chinetti in 1958.

The 600 GTO is due to make its debut at the Frankfurt motor show in September.
