I think having the 5er without the alu buttons is a good way of differentiating the interior from the G11 one. I wouldn´t mind if not even the luxury line had it as an option.
Having them as an option never hurts, but I also think the black buttons have a sporty touch and maybe suit the 5er better. Still I want to see the luxury line interior too. Should really be a mini 7er.
