I just took European delivery of my 650i convertible in Munich, Germany. I loved every minute that I spent in the car. I am already in withdrawal waiting for the car to arrive in Atlanta! Even though I was babying the engine for the 1200 mile break-in period, I was still amazed at the power and performance even though the rpms didn't exceed 4500. I was even able to go 150 mph on the autobahn and not go past 4500 rpms. In a word: WOW!
Overall feel and performance, the heads up display, active cruise control, active steering and voice commands.
