-race truck - circuit racing trucks, need no special track
-nascar - ky oval people would love these
-sports prototypes - we have a lot of gt fans on lfs so i think these would work - LFS le mans 24hr
-touring cars - would suit all tracks and be a great addition
-a kart may be a bit of a novelty but as it probably will get as much use as the mrt its a -1 from me
- Also a SUV type vehicle would be good for using as a tow - for cruise and circuit racing (where mid race join is unavailable)
