I changed my mind. I used to like Forza 2 more because it was more realistic, but I just pulled out my steering wheel and pedals and tried to play again yesterday and decided that I now hate the game.
I built up an E46 M3 and couldn't keep it around the track fast for more than a couple of laps before it would understeer into the grass or a wall.
I'm switching to the GT5 camp so I can play an easy game!
