Here you go. Your texturing is way better than mine. The dark line on the car is down to the GSID working overtime on a seam in the model. If I were taking this further I'd probably do a separate render of the car and comp it in post. I think this is the same model as you used, from Foundation3D? I had to scale it down to 0.1 but I don't know how big a cadillac is really anyway
tgd attached as well.
just noticed the grid patten showing upon the car. Looks like it's following the bucket edges.
I'm sure you can tweak it way better (and use your better car )
the somewhat rediculus render settings were simply because I let it render over night and thought "why not!"
