 I owned a 2005 BMW 745i, which I considered the "Ultimate Driving Machine" prior to purchasing the 2012 BMW 750 Li X. Shortly after purchasing the vehicle, I noticed the wind noise and road noise was almost unbearable. I complained to the service advisors and was told that either they couldn't hear any unusual noise, then it was the road, then it was the run-flat tires. The adaptive headlights provides poor night vision on dark roads, drivers seat material worn excessive at 40, 000 miles, there is vibration during takeoff, there is little to no storage space for cell phones, etc, in the console or glove boxes.  When steering wheel is adjusted for me, mileage, temperature, and navigation controls are obstructed. vehicle feels heavy, bulky, and requires a firm grip handling. Cargo space is rather small for such a large sedan.
