Spreading the brand too thin?

[hownnq]

Guys, just wanted to get your perspective on whether or not BMW is spreading the model line too much. What I mean by that is, I\'ve noticed that they have been adding various models their lineup. Various editions of the m3 various editions of the 3 series coupe just to name a few. My point here is, that if they do saturate the market with new vehicles do you think they will loose their sense of uniqueness. On top of that do you think the quality may suffer both in vehicle quality and service quality based on such saturation. It would be great to see what others think.

Thanks
