Ferrari has revealed its latest one-off project, the Ferrari Superamerica 45. It was built for Peter Kalikow, a New York real estate hot-shot and Superamerica enthusiast who also owns a very special 1961 Ferrari 400 Superamerica cabriolet. The 45 will debut at the 2011 Concorso d'Eleganza Villa d'Este in Italy this weekend.

The car is based on the Ferrari 599 Fiorano and features a targa-style roof with a freshly scultped rear buttress. It also gets a carbon fibre rotating hard-top which can be opened, and a redesigned carbon fibre boot which is capable of storing the roof when it's flipped back.

Other highlights include the Blu Antille exterior paint which is said to match the owners original 1961 Ferrari 400 Superamerica, special two-tone machined alloy wheels with Blu Antille accents, burnished aluminium A-pillars and side mirrors, and unique double gill vents on the front guards.

The interior of the car has been customised to match the exterior and showcases Cuoio leather trim and Blu Scuro carbon fiber details. It also features Ferrari's latest touchscreen infotainment system in the dash.

Neither the owner or Ferrari has disclosed the cost of such project, but we're guessing somewhere in the millions. This is the only example that will ever be made.
