Ya probably, I don't have much interest in NASCAR but he mentioned it so I found the codes in the game data for him. Didn't know you could buy them.
The gamestop one crashes the PS3. I'm thinking there is something marking it as not available unless you own the DLC.
By the way: the colour code names seem to be encrypted, either that or I have not found them yet. Only looked once though
