It now has its proper wheels! I also discovered something interesting. The software I use has a smoothing process called Phong Shading which smooths out the angles between the polygon points on a surface. By default it smooths every angle up to 90°. There's an option to change that angle range which can have a dramatic effect on the lines and edges of your object. Here's a couple of snapshots that show the Phong angle reduced so it allows more sharp edges to show. This makes everything look crisp and sharp, but the downside is it also doesn't cover up any "issues" so you see EVERY spot on your mesh where the point geometry is slightly off. This of course requires lots of small adjustments to fix the mesh but once you do the results are impressive.
In these two images you can see how much more defined the edges are on the back of the car.
The rear fenders stick out too far so I'm going to have to pull those in, which is not going to be a quick or easy process but it needs to be done.
