I highly recommend mineral gray and have it on my 2012 Overland with saddle interior. Those two colors together look incredibly classy and rich. One thing that I really like that has been mentioned is that mineral gray still has a very deep shine for those that like to keep their cars detailed and clean. And ofcourse since its a gray it hides dirt and blemishes (not that I have any;-) incredibly well.
Last but not least and this is something I have not seen mentioned yet. This color also looks strikingly good in cloudy, gloomy days where as most colors just kind of look blah in those lighting conditions. Some of the sweetest views of my Jeep were when it was all clean, but on not so sunny days. It goes really well with chrome as well which is a good thing for those Overland guys. IMO its an all around excellent color.
