A one-off Pagani Zonda is being built for an unknown, and obviously rich, American enthusiast. Know as the Pagani Zonda HH, the car will feature various bits of the best Zonda versions.

Pagani Zonda HH

There's elements of Zonda F; in the form of the carbon fibre body panels and front guard-mounted wing mirrors, and also elements of the Zonda Cinque; in the form and sound of the 7.3-litre, 506kW V12 engine.

That magnificent engine is mated to a full-manual transmission, none of that dual-clutch stuff here, which is all bolted onto a complete carbon fibre and titanium chassis tub. Underneath, there's a titanium exhaust system for that clean crisp sound. It seems the owner has good taste.

Although the vehicle isn't completely finished yet, the colour is said to be a Monterey Blue using yellow highlights and decals. Keen Zonda fans may also notice the revised, carbon fibre, rear air-intake snorkels for the engine. These have been added for further exclusivity.

It's not clear as to who the lucky owner is exactly but rumours have it 'HH' could be the initials of the buyer.

You've heard of tailor made suits, here's the tailor made Zonda.
