Thanks!

If ya don't like green there's plenty of red!

Deep Red, Burgundy Red, Cherry Red, Red, Hyper Red

 

I've got that car paint material but I can't seem to get the result bb gets here, especially in the middle one. I think he was talking about a much more advanced shader that I probably could never understand. My math's elementary level at best :)
Ooops, no pic. It's in page 3, the post with the row of red cars!
