2012 BMW 650 M Sport
 I owned a 2009 650 convertible for three year and never had a second's trouble with it.I now have a 2012 650 convertible with M Sport and the Bang and Olfsen sound system.This is the most amazing car that I have ever owned.The power is unreal, it can float across potholes (in Comfort + mode) or feel as connected to the road as the old M6.It is stunning to look at, especially in white, but the best part about the car is the new Bang sound system.It is crystal clear and LOUD enough to shake your clothes.You can describe it.You have to hear it.I'm sorry about the post above that had a problem in the rain.So far, mine is better than my first one.
