2012 BMW 6 Series 640i 2dr Coupe (3.0L 6cyl Turbo 8A)
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.
Bang and Olfsen sound system--it even rewinds songs played on the radio.
M-Sport package--with 20" rims
Camera package--looks around corners so you don't get your front end wacked at tough intersections, parks itself, birds eye view all around the car for parking or backing up, reverse camera, blind spot warning, lane departure warning
Leather dash board--elevates the interior to new highs in auto design
Back seat should be bigger.
For such a big car, the back seat is smaller than in the 335.
