The RS was only available in the phase 2 (facelift version). The facelift could be added once the phase 1 model is finished, but for now it's not a priority. The Sedan can also be added, which should not be too difficult as I can work from the 5door JBeam and mesh once they are finished.
it's a purposely total dogshit butchered version of a mod with everything on it completely ruined (model, textures, jbeam, just about everything else) it's also stolen from about 3 different places good luck getting absolutely anywhere at all with that because it was made specifically to be unusably bad
