Ah yes, the Pagiani Zonda, comes in many flavors now.
The C12 was first, debuted at Pebble Beach back in 1999, I remember when I first saw that car, and the exhaust design, and I was blown away.
The faster C12-S, then the C12-S Roadster, then the C12-S Monza that is now FIA GT approved, and my new favorite:
The C12-F and C12-F Roadster, which comes in full carbon fiber. And I mean that when I say it:
Named after Juan Manuel Fangio, who helped make this car a possibility for Pagani. Carbon Fiber isn't exactly an easy or cheap material to work with, but well worth the reward, and to make a car completely out of Carbon Fiber (CF for short), is a masterpiece. Only 25 were made, and they will never be made again.
We have a small Pagani page on lifeinitaly under the car section, check it out, definitely one of my favorite supercars sinces its debut.
