there is a good list of cars for you to search for!
but by the late 90s the Group N and WRC cars were running about the same lap times on many of the same courses... so does 600 primitive HP really turn me on? Nope

cause all it does is go straight!
Also this is part of the big rule change to happen in 2010 .... The cars are rediculously fast again, and the only manufactuers that can afford to compete are Subaru Ford and Citroen...
