oh shit it worked! my friend has the gamestop ce and i created a user account and logged into his psn, went to the downloads and downloaded the additional cars, then went back to my user account and the game added the cars!! wooooo
So yeah find someone willing to do it.
The sls amg at the bottom is my original amazon car, those above are all gamestop cars.
Did anyone get the GTR or NSX preorders? Ill trade you for the sls amg
