How is the Ferrari F40 one of the fastest cars in Gran Turismo 5?

All over the internet it is the third fastest car in the game, but i have lots of faster cars than it. Maybe I just didnt tune it right.|||Considering that the F40 is a twin turbo, aerodynamics that were way ahead of its time, and was essentially built for nothing more than going very fast, I'd say you don't have it tuned right. :)|||It's fast, but it was only the "fastest" car in Gran Turismo 5 Prologue. In the full version of the game, there are a handful of cars that would beat it under most circumstances.
