I understand that the Japanese version had 4 extra F1 cars, a Diablo, and a 911 and Stratos in road and rally forms. What I was thinking was, if I get the Japanese version off eBay or somewhere -would this play on my UK PS3 - then I would have ALL the cars (albeit on two discs/saves) Better still are those cars available in the US version (to play on UK PS3 that is)
