A little fix in the car model

I have a render that I want to take up a notch with Mental Ray but am having a small hangup in Maya getting the global illumination to make the reflections and overall look just 'pop.' All that I would require is a gentle nudge in the right direction and for a professional should only take a few moments to look at my scene to make the correction to my shader and get it working properly.

So here is the deal. I purchased cars which I need to essentially get the shader to live within a global illumination "bubble" which I can use to render from directly overhead (top down). The shaders that came with it don't really work despite the company saying they should. And I don't know if what I have will just slow you down or not, I'm thinking I could just give you the model and get the scene with shader network back from you.

I will be swapping the car model out and applying this to other cars, which I would think doing so would only require me to re-apply the shaders and to adjust color/diffuse as needed.

Does this sound like something you have the time to do now?
