There are companies who specifically rent race prepped cars for the nurburgring. http://www.rent-racecar.de/ is one.
No amount of Forza will prepare you for the real thing. It'll help but likely will make you cocky and foolish. I only say that because I've experienced it first hand. I almost crashed in a buddies STI because he went too fast because he "knew the track from Forza". Nevertheless, even driving safe it's often the other stupid drivers that crash into you! And a M3 in euros would not be fun to try and pay off.
I was joking about the Forza 3. I know it will be nothing in real life. Never the less, I've been talking to my friend over there. He knows some nice country roads to practice on. Ha
