You really think it's that ugly? I chose it because I think it looks fantastic when using a wide angle on the front end. Also partly because it's the only race car I have that was suited for the job, the Toyota 7 or R89C would not look at all I think.
What I mean with highlighting and shading is to work more around light sources. You know how all the cars look like a flat piece of cardboard on stock shots? I tried to fix that by trying to give the car more depth with the dodge and burn tool, not only on the panel gaps but on the whole body. It's pretty much a trademark of Alexwrc, and for longer I've wanted to try it myself. The first time I successfully tried it was with the Delta Rally car some pages back, but this time I wanted it to give more impact.
Here's the original, it looked really nasty and the car looked like a flat piece of cardboard glued to the background:
