Remove that car folder and see if it works now. Maybe you didn't install this mod correctly. Also check your resolution in game. Afterwards if it doesn't work, go to steam library and verify cache of AC, in (right click) properties, local files tab.
Also, confirm that when you placed the f12002 car folder you did it in the right place. Sometimes it can happen with a distraction. So you don't have something like \content\cars\content\cars\f12002 or some other problem with dir structure.
