Yo Tristan stop bashing hatchbacks and go take a drive in , for example, a Type-R, Focus RS or the new Golf GTi. You'll be suprised!
AFAIK a game called "Racer" has a Nordschleife-mod too. I think it's data came from GPS and it's damn sweet & accurate. And this game is made by 1 person. I'm too lazy to find more info about it but I'm sure you can Tristan
