I think what a lot of people liked about Auto Modellista was that you could customize your car and garage accordingly. Of course to many, the game was a disappointment. What stood out to me was, of course, customization. I know I talked with Eagle in my "The Debut of LMP Race Cars" topic, and he mentioned having red cars for my genetically-called team name of "Eagle Motorsports." So if you wanted to make a car a racer, you'd just stylize your car accordingly. But if you ask me, I don't mind doing my cars the way I want to design them. I'm sure there may be some skins you can use for generic paint schemes (such as Gran Turismo, Castrol, Mobil 1, Texaco, and stuff like that).
Oh, and one more thing... if paint was implemented, I'd like to have the old Castrol colors for the Tom's GT500 Supra before moving to this weird paintscheme late in 2001. Then, it would be nice to see the Castrol Supra from the first Gran Turismo. I think this car was pretty popular and was very noticable in Gran Turismo. So why not bring it back? Nostalgia, people! And of course, the race car from 1996 would make its debut on PS2, so it will probably look shiny and cool compared to its GT1 and GT2 counterparts.
