I think I may do that in some spare time. The coming version is basically a colour change, possibly new rims, and faired in rear wells. But I think it would look nice with more.
I used Illustrator, but with lots and lots of layers. And gradient fills. That one has a couple gradient meshes as well actually, as there were some complex curves to replicate.
This looks like it came right out of the 1947 Pontiac brochure! Very detailed metallic highlights really make this pic stand out. Excellent work on this one.
