I'm obviously biased since this is the color I have but I almost got SGM and am glad i didn't (although all the colors are incredible). The Montego takes on so many different colors and catches the light nicely so you see different shades of blue which highlight all the curves. I am not particularly fond of the bottom side skit (pot belly) curve or the headlights but this color doesn't seem to over accentuate these curves IMO. Sometimes the blue takes on a bit of an indigo blue which I like a lot. Good luck.
