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.
Road cars, sports cars, race cars.. Personally, I prefer race cars and spectacular oldskool ones from 60's and 70's in "Victory by Design" series. But this is just a dream. And I've realized that I have no expectations for car suggestions anymore. I'm too old for waiting and it takes too long to implementing for devs.
The more the merrier,
But if I have to be specific. I like civilian type cars, so anything far and in between a Honda R or a Skyline GTR. Everything Nissan, nothing hyundai. I'm hoping Forza volume, but would prefer quality over quantity.
I haven't seen trough all 131 posts, but I wanna see Toyota AE86 and something like Skyline R32 or R34. And maybe some Eco cars just for fun. (Gran Turismo 4 features a f*ckin' Prius so why not?)
