Probably been already asked and answered, but is it possible to engineer in some way, a method of racing in the same classic cars with different skins on them? Ie is it possible to reasonably replicate a full grid of teams (be it single race, career, championship etc) with real names and liveries. I know the name thing isn't too much of a problem, but the liveries on the other hand...
I suspect it isn't possible given that I haven't seen any mods for it already and I imagine that it'd be a pretty popular thing.
