I gave up on the 350Z because I didn't build the surfaces too well, and it was too far along to go back and fix stuff (big problem with nurbs is that if you delete history on a surface, it can be hard to fix stuff without messing up other parts). I described the lighting set-up earlier. It's just a large area light, with 2 directional lights casting soft raytraced shadows. I'm ditching the whole HDRI lighting thing until I'm good a studio lighting, then I might go back and do some HDRI renders.
