I like that idea Seth!
Maybe we could just do a class(S, A, B, C, D, ect) then drive type(RWD, AWD, FWD, or Any). Then pick a track to go along with that weekly.
That way it doesn't require you to have a certain vehicle and it'll keep things more interesting. Because an A-Class BMW M3 might be quicker around the track than an A-Class 350Z, or ect.
