Hey, an old post to which I can contribute since someone else bumped it first!
I made my purchase choice based on options, availability, and price. I had no preference in color beyond NO SILVER/GRAY. My husband's last two cars were silver and gunmetal gray. Mine were green and blue. I need color in my life.
Can't get more colorful than IOM.
(though shhhhhh I actually like the CGM)
