2006 BMW 6 Series Convertible 650i 2dr Convertible (4.8L 8cyl 6M)
The Ultimate Driving Machine
 In January, I traded a 1996 Porsche 911 C4 Cabriolet for the BMW 650 C Convertible.  This was the first vehicle that had the WOW factor for me since the Porsche.  BMW does a much better job with both interior and exterior finish than BMW, has a better warranty, better service, and now  has built a coupe that handles as well as the Porsche.  The upgraded sound system blows you away and the car is teaching me how to use voice commands. I'm learning.  Steering is responsive, acceleration is as good as the 96 Porsche, it is more comfortable than the BMW X-5 I own and I can't find anything BMW has left out.  GREAT AUTOMOBILE!!  If you can afford own, buy it.
