I have owned Mercedes for the last ten years I owned a Porsche and Jaguar. This is the first BMW I am totally pleased with my 650, its the fastest car I have ever owned, and the interior is not only beautiful but very user friendly, I recommend this car to anyone that enjoys driving.
Quite frankly my favorite feature is the power. Then all the toys are great the car has it all comfort, speed and looks.
I would suggest two improvements, One is the back seat and two is the rear style of the car I think a little to radicle, it might grow on me. But the handling and speed make up for that
