Your tutorial is great it has got me started on 3ds max, I am sure with some more time I can do a lot more!
Here is what I finished with, unfinished but still got some .dds files that I had downloaded for in LFS that I used with some different brake discs. I kinda just decided to split up the layers into new layers so I could add different maps to it.
I turned the wheel a bit to make it look like its posing lol.
Things that I still need to do (which is probably obvious) are:
1) Make the tyres black. I can't figure out how to do this.

and add a LFS tyre wall with logo.
2) I would like to put an image on X Y and Z plane so it looks like a background, or a floor or something other than floating in space.
3) I would like to get some real reflections going on. Lighting sounds complicated but I would like some ripples type reflections.
4) A shadow under the car.
5) Some custom grills on the places where the skin is very small, do I just do this bit with photoshop?
Anyways, thanks again for the tutorial and help, hope you think I did ok so far!
