I had an F31 in alpine white which looked good with exterior black bits and pieces.
I'm in a 440i GC now in carbon black which is a great colour but not available on the G31. Darker than Tanzanite.
I thinking about an M340i xDrive tourer for next year and wil probably go black sapphire metallic, given the limited standard colour choice. Pig to maintain but once professionally detailed, easy to wash and fantastic to behold when clean
