My friend is a big fan of the CGM as well. It does look cool, but I'd rather go pure black or pure silver. I've already owned a black car and it was a BEAR to keep clean. This time it's silver all the way. Honestly I think it's the sharpest color for this car - my taste is somewhat skewed by the fact that my first muscle car was a 1970 Pontiac LeMans which was silver with a black vinyl top - and I LOVED that color.
I did consider the Yellow or Orange as well as "standout" colors - but I decided against it. Also "standout" colors standout to cops more too
