I never have understood cars that are silver or gray with a beige interior. It looks wrong even in the BMW brochure.

I think everyone gets Space Gray, but if you must do so, then I'd suggest Black leather with aluminium trim. Titanium Silver is a nice hue for the exterior.

I'd skip Smartphone integration, I would order Sport Activity Package. Prevents too many colours inside since it has the anthracite headliner. The Aluminium trim will break it up.

I would skip the Premium sound unless you're an audiophile. Money can be better spent on the ZAP.
