Bump on the interior colors, although the line (except for the nav screen) are nice. I am thinking though, that a rich single color might really look nice, and emphasize the lines and proportions of the interior...deep tan, saddle brown?
To the nave screen, I hope that it could be better incorporated into the production car dash. It looks like an afterthought, stuck onto an otherwise nice design. With all the functions communicated via these screens in modern cars, a fixed, not articulated design (the new Audi A8 as an example of how not to do it) is appropriate. This thing looks like an old tombstone!
As to the cup holders, leaving them out altogether would suit me, although they can be handy. On my E63, the was an expensive, kluge-y work of art, that never came out of its hider. I threatened to remove it, mount it on a handsome piece of marble at an odd angle, and auction it as a piece of art. Such things are like re-dos of music or movies: do it clearly better, or skip it altogether.
Except for the nav screen though, there are solutions (unless BMW forces two-tone interiors on us) that are workable. With their growing emphasis on permitting buyers to equip their cars the way we want, we should be able to option our way around most of this.
