Does the roadster come in the darker grey/silver color in any other year other than the 07's?

 

Every year has some variation of silver and/or grey, some lighter, some darker.

 

This does not answer your question, but I saw an 07 Black roadster at our recent Z Club meeting. That is a real sharp looking black. I have an 04 black roadster and I thought that looked pretty good. But the 07 has a metallic flake in it. Looks like a custom paint job. Really, awsome looking.
