NFS Underground Trainer\Cheat

[Dynamite]

I just finished NFS Underground and it said everythin is now unlocked.
But it didnt actually unlock everthin. Does anybody now if theres a cheat or a trainer that unlocks all of samanthas custom vinyls and the other wide body kit. Cos theres about 10 of samanthas vinyls but u only get to pick 1 and theres 2 wide body kits but u only get 1. I checked all of the cheats and trainers on GCW but they dont have a cheat or a trainer to unlock them.
Im kinda annoyed cos i finished the game but didnt get absolutely everthin
