i still have to do the historic car championship on expert and allstars..
Personally I play the level 20 Nurburgring race over and over. Mainly because I love Nurburgring and the money is not too shabby. 59,000 in roughly 7~ minutes. Plus you get really familiar with the track.
PS: Best time 6.51 with Audi R8 5.2![]()
