I preordered from gamestop and should have received the McLaren F1 and a NASCAR stealth car but didn't receive the codes with the game(my girlfriend picked my copy up for me). I'm wondering if they are worth calling GS about the matter or if they really aren't all that much. Can you upgrade a regular F1 to the performance of the stealth version or do they have added performance you can't get in the tune shop?
