If you've spent millions buying Ferraris over 45 years, what do you buy next? If you're New York property magnate Peter Kalikow, you order a one-off Ferrari that no-one else can buy.
Ferrari has revealed a unique supercar commissioned by one of its longest-running customers, with the Superamerica 45 going on display at this weekend's Concorso d'Eleganza Villa d'Este in Italy.
The 45 was designed and engineered by Ferrari and looks like a cross between the prancing horse brand's 2003 575M Superamerica and 2010 599-based SA Aperta roadster models.
Kalikow's newest addition to his car collection that's reported to be worth about $6.5m features a carbon-fibre roof section that rotates so it can be accommodated by the specially designed boot for open-air motoring.
Further flourishes for the Ferrari include the application of special chrome for the grille and the use of burnished aluminium for the windscreen pillars, side mirrors and doorhandles.
The Superamerica 45 is coated in an exclusive paint colour Ferrari calls Blu Antille, with matching alloy wheels.
Aerodynamic body parts that help to create downforce - including the front splitter and rear diffuser - are made from dark blue carbon-fibre, as are the side sills.
The dark blue carbon-fibre is also used for the dash and driver's cockpit area.
Ferrari hasn't revealed the cost of the bespoke supercar or who paid for it.
