I think those wheels are also exclusive to 650 M Sports. The 640 has a different 20" rim, I believe...
Wait, are you saying that BMW is publishing false information?!?!?!?! Especially regarding the 2012 6er?!?!
Their team really fell apart with getting their facts straight. I did, however, complain about the non-auto trunk, no soft-close, and no shadowline (especially the great expense aftermarket for something that should be included in a $4400 package) in my post-purchase survey where it asks about suggestions for BMW engineers. The dealer and sales team were great, I figured this was a good chance to voice some of these problems in a form that has a chance of being read by someone who might care - for half a second before it gets thrown into a stack with 100 other surveys lol.
