We did a lot of work on that Moonstone E90 M3 and it has a incredible amount of depth. At a quick glance I can see how the color goes unappreciated, but when you have the opportunity to see it in every type of lighting you grow to appreciate it. Here are a couple photos of the E90 M3. Overall I believe this color is better suited for a F10/F11 chassis than a E90. Good choice IMO
