Personnaly what I would like is that we get some real off-road racing.
Full off-road track, rally cars and 4x4 (speaking of real off-roaders here, not stuff like Escalades)
What would also be nice is a V8 muscle car balanced with either the TBOs or the LRFs. It could even be equiped with a solid rear axle like on 'stangs before the current generation.
