I don't think its as good looking as the 599 GTB but its still gorgeous. It has a version of the 4.3 V8 in the F430 producing a slightly less 454bhp. Although a brand new 7-speed dual clutch transmission allows it to accelerate just as fast or even quicker than the F430. The California features a retractable hardtop just like the Mercedes SL.
