ok i have bought all expantion packs and i dont know where all the cars are can someone help am i ment to click something or what can someone help me

You need to install it after you download it, go into the game part of the XMB and they should be there, then go onto the games, the cars should be there, if not then download them again, dont worry its free when you download them again from the 'Downloads' menu on the PS Store

Speaking of DLC, any sign of the Police Car Pack in EU Store.

Question: I am probably going to pick up this game before the holidays and obviously if I like it I want the Premium South Central pack. But one of the things I have found in racing game DLC's is that the "car packs" tend to be either completely useless but cool novelties or they are good vehicles. I personally could care less about "pimped out ride" DLC's that add nothing to the game for me, but if some of the vehicles you can purchase will actually give me an ADVANTAGE against the AI in the career races (which I hear can be pretty tough) then I would buy them. Again, I don't care about things like, "Oh wow that Escalade looks so cool!" What I want is vehicles that are actually HELPFUL and/or at least REALLY FAST in the game.
