Im sorry guys im new at this stuff.
Ok, the problem was that their was no Model.cfg, I made one and put that in the folder of the car so P:\impala and it is on the ground now and not inside it,
For the texture
It was a simple mistake as it was in my P folder and than in CA when it needs to be just in the P folder. Once i did that i renamed the textures to \impala\textures\texture.paa and it worked
