I am not going to pretend to have any experience driving any Ferrari, but I am yet to see/read a test of an F40 that has said anything other than they are one of the greatest drivers cars of all time. As for the Carbon chassis, bare in mind the first carbon tub in F1 had only happened 5 years prior to the F40, and would not be part of a road car for another 5 years, even then in the massively expensive/unsuccesful Mclaren F1 (Yes it has it's own place in history, and it took a W16 with 4 turbos to beat it). To me the R33 GTR is a better car than the R32 in MANY ways, but the fact that the R32 is a little more of a mongrel is part of the appeal (and reason I bought it). The F40 takes this much further, it is badly built, it is uncomfortable, but I get the impression when you get it right there is nothing comes close. Porkas to me are just proof that engineers can overcome physics, and that Ze Germans are too stubborn to just fix the problem. That's my opinion..
