I own Race07. being the Nordschliefe already available as third-party creation and being me interested mainly in F3000 cars I do not see any points to upgrade to EVO.
i bought already and its really nice even the Nordschleife and also the ghost car or that you can upload another drivers best time and see the drive line from him . i like it very much to become faster ( sorry for my bad english )
I got it about a week after it came out and I'm LOVING it. The car physics are vastly superior to GTR2. So much so that I un-installed GTR2 from my PC and never plan on playing GTR2 again!
