Opinions about a body color are like assholes, everyone has one. I hate the Silver Stone color, I almost ordered mine in that gay ass baby blue color until I saw it in person. But hey, that's just my opinion and I'm glad I got Space Gray Metallic.
lol! I'm just adding drama to this thread. Its not a bad color and I liked in the sun, just too baby blue for my taste when I saw it in the shade. Enjoy your M3 no matter what color it is!
