Unique Pagani Zonda HH pics leak out

Pictures have leaked out of the Pagani Zonda HH, a one-off creation that was commissioned by an anonymous American customer.

The specially created supercar is based on the existing Zonda F Roadster, and shares many of that car's components. However, it also takes the very best bits from all the special edition versions of the Zonda that Pagani has produced since the car's launch.
