Well, the trading limit is one car... Which one of those 17 are you interested in?
Also, most of the cars I have are premium race cars, so name one and I may have it. Mazda 787B, Audi R10, Peugot 908 HDI FAP ect.
Thanks again Dougie. I'm only going to use it with B-spec mode, for now. People say once you drive it, it kind of makes the slower cars seem boring and ruins the game. Haha.
