Of what I browsed on the bmw.de site about the F10 my choice could be:

Color: Sophistograu Brillianteffect (or Imperialblau Brillianteffect)

Inside: Lether Venetobeige

Trims: Edelholz Esche dunkel

Wheels: Styling 332 (or 331)

The extras must be decided later on...

The 523i means that a stronger 525i will come in a couple of years,
and the same goes for the 528i, it will be a 530i, when they get the turbo
engine ready.

Also that the 535i comes only with the 306 hp engine will mean,
that at least 330 hp 535i will come after two years.
