Yeah, listen to Matthew
Stratus Gray is very funky in person. When I saw it on the 650i I drove 3 weeks ago, at first I thought it was an awesome metallic gray. As I got closer, it started turning really brown, with odd hints of turquoise and green, while kinda looking bronze. It is just an odd combination!
I personally think Sterling Gray is much, much nicer. It is classic, and is much better for resale or trade-in value.
