I sure wish we had an X-pack of low-poly, photo-textured cars. Sorted by decade. When I say low-poly, I'm thinking of typical trackside cars with <1,000 polygons, preferably <100. A step above the "box car" tutorials. Sad thing about undertaking such a project is that there are sooo many models to create! I could be persuaded to go on a photo-taking expedition if someone can quickly make the models.
