It's the perfect time to comment as the maker will be at the perfect stage to make changes.
I think it's a pretty good model so far - the roof, rear window and boot lid could do with a higher polycount to match the front window and bonnet, and there are a few polys around that could be combined to reduce the vertex/edge count and make the mesh cleaner, such as the sills, front bumper, under the rear quarter-light and above the front arches on the wingtops.
Can you post a smooth-shaded image without the wireframe?
