I personally like Forza Motorsport. Not sure which one I played (maybe 3), but it was great. Tons of cars and, like you, I don't usually play any type of sports games. Including racing, but I made an exception here and there with Forza and Need for Speed, and Midnight Club (PSP). Haven't played any in a while, though, but those are the one I've played and consider at least remotely enjoyable.
