Hi Randy,
Nice shot. One thing I noticed is those cars we commonly use is they have an error in the ORTS log about some missing "gloss map" - so I started playing around - while not a huge fan of "specular" - if you open the automobile shapes in ShapeFixer and change the "shine level" to the highest shine - they look far better than the flat paint. Might want to try it and see if you like it.
Regards,
Scott
