Trollsville, Nebraska. Good thing about the DLC: it's optional
Not too bothered about the oval track (don't really get the point of 'high speed testing') but I know others like it. Of more interest is the New Lambo. 100% on this one.
Some of those cars weren't even commercially sold until after GT5's release.
Go and take your hate somewhere else, it's unwelcome here.
No one is forcing you to do anything with your money. GT5' isn't the only game with DLC, and we are not to judge what should have been in the game at release.
