Zonda, no doubt. Got nothing but good reviews. Looks special, is luxurious and handles great.
CGT... don't really like the back.
Koenigsegg. Looks good, but I've known it for years (seen some prototypes before) and the design gets a tiny little bit boring after time. :roll:
I've never really liked the SLR. Mercedes came up with it it right after their mereger with Chrysler and I think it looks too American.
