I hope so to, there are more than enough cars in the game already and it's not like you will ever use half of them. I'm 80% through the game and I'm getting a little bored with the tracks already.
As for the crashing thing, like it's been said before, you hear about all the worst cases and get no real prespective on how bad the problems really are. I'm the same as Tarrife, I've had FM2 in my 360 since the 18th of last month and it's not been out yet, also been playing at least an hour a day with a couple of 5 hour sessions. I won't say I have not had any problems, I've had the "can't read disc" error twice now, once while racing and once while it was saving the game.
