Then they should be automatically in your garage.. I have the Chrome line and a few other special cars and whenever I make a new account on my ps3 for birthday tickets or whatever reason, they go directly in the garage, is your account the master account on your PS3? If not you need to redownload them from the original account you downloaded them from at the PSN store. Otherwise I have no idea what to tell you, if you got them through account share then you are prob screwed, but if you got everthing legitimately I would definitely call Sony and or Polyphony Digital and demand you get what's yours!
