For our group it seems that the Carrera NASCAR is the favorite class. They run real well with just a bit of tire truing and they seem to be bullet proof! We all have at least two just for some varity. Most of the guys have done a repaint. Not a single Carrera stocker has ever stopped working, and I think everyone of our cars has been involved is some pretty serious crashes, seeing the floor before it is over! I don't know how they put up with it but they just keep going!
All of our new drivers have improved as they run a few sessions and the crashing on our tracks is typically from the routed shuffle in the banked corner. It takes A LOT of patience before everyone learns to drive the lane shuffle without a wreck, but not one of us would have it any other way!
You can see in the above photo, the outside lane crosses the other two lanes going from outside to inside.
