There is alot of crappy cars, but its understandable, since most of them were not concieved to be fast, or to be knowned as the best car in the planet (like the Tank Car), so I have nothing against them, and don´t expect alot from them either, I just have fun with them. Or cars that we expect them to be fast, just because they were considered the best 20 years ago(like the F40)
But the "almighty Enzo," It was supposed to be the fastest Ferrari on the planet, but its not even able to beat its younger and cheaper brothers (plus a low-tech-truck-engined-american-sportscar).
