Last week word broke that an unnamed American buyer had commissioned a special one-off Pagani Zonda "HH" model, and today we have the first full images of the car. Expected to be based on a mashup of the Zonda Cinque and Zonda F Roadster, the HH roadster could make its public debut this fall at the Paris Auto Show.

Power should come from the same Mercedes-sourced 7.3-liter V-12 engine rated at 680-horsepower and 576 pound-feet of torque found in other Zondas, delivering 0-62 mph times in the 3.4-second range and a top speed in excess of 217 mph. Not bad for a convertible.

Price, as with any Zonda, but particularly a commissioned special-edition, will be in the stratosphere: expect seven digits on the receipt.

Pagani hasn't released any official information on the car yet, but we'll bring you the latest as it breaks.
