You keep insulting and you say you are done LOL. And seriously you talk like the typical noob that stick to rFactor central and doesn't have a clue on what's goin on in other sites. High poly models convertions with proper shading, templates and interiors?

Seriously you don't know what you are talking about, Rfactorcentral is the old stuff and it DOES NOT represent all the Rfactor mods. How you can quantify the number of mods available on the net? There are simply too many sites and for every crap mod there's a great one so the 80% thing doesn't make sense. Enduracers mod with Add-on cars is a game by its own.

SandroX on his blog has released:
Pagani Huraya,
Maserati Gran Turismo,
Radical and many other cars and series. With modding games you have to know where to look at, there are so many sites, use google, search the right forums, keep the good stuff, trash the s***, have fun with the good stuff. It's a different approach from normal games but it's very rewarding once you know how things works.
About GTR2 I tell you these two modders, Merlin and Mac10. I've just downloaded the complete GT3 class, BMW Alpina B6, Matech Ford GT, Gallardo LP 560 GT3 etc.. All great high poly stuff, if they'll accept you on their sites you'll understand.
