Like most people here, the J2 and Toyota 7 are my least favorite cars in GT5.
Even more fun to watch when it comes down to the finish line, the top 3-4 cars finish with in 0.01th of a second from each other, as well as 15-20 other cars finishing in the next second or two.
Personally, NASCAR is my favorite motor sport. Where else do you see 43 cars racing at 200 mph all bumping bumpers and the time distance from first to last is 3-5 seconds? No where.
BTW, this is coming from a guy who has watched 24H Le Mans, F1, Touring Car Championships and WRC all his life.
Grow up guys.
