AL: What you said about the design growing on you is just what the designer intends!. So it seems, there is some merit to the design brilliance of Bangle et al. Now, the protege, Adrian Hoonydonk!. The Dutch guy.
True. Design estatics is very subjective and personal to everyone. Hard-core/hard-headed traditionalist cannot swallow designs from E39 onwards for 5-series. There are lots of these people in BimmerForum US and European forums. They puke at E60 particularly. Actually so many in the US market has, that , they went to Porsche!. Interesting, isn't it. Didn't head for Benz or Audi.
Is this a class change in the enthusiast segment for those whose affluence has increased to the level of Porsche affordability ?. Maybe so.
There are ones willing to compromise and gradually move with the BMW range. BMW , of course hope, this is the majority of the case. But it seems they wanted to EXPAND market share more so, by attracting buyers from other marques. It is a general Corporate challenge most companies are faced with these days.
I am sure they can sustain the growth despite controversy in model looks. The "face-lift" models tends to correct the worse of the initial visual impact. I can agree on this except for the E46 face-lift model. I prefer the pre-facelift E46, any day.
