Alright, alright, I learned my lesson about modding and how it can't happen without SIGNIFICANT and nearly impossible progress.
Now that that's out of the way, how about unlocking "secret cars". As in, cars that are in the game's files that were unlocked with programs like ArtMoney back when the game was officially online. Before, these were only visual, but I have a feeling that they can be fully added now, even if only available as another version / body variant of a similar car. (i.e. the widebody BMWM3GTR being available as another, seperate car to purchase in the store)
I am now awaiting "the roast" from you bunch of savages and being told too look at my post about modding for answers.
