Fun to drive the 750il. Takes time to learn all the features. The gas mileage isn't bad for a V-8. I love the room in the back seat. The navigation system is entertaining but somewhat distracting. Same with changing the radio stations using the iDrive. No problem with the blackberry after t-mobile made some changes in the cell phone program. I have had no reliability problems.
Navigation system, iDrive, room for seating, the drawers for change, acceleration.
The side view mirrors should electrically close for the cost of the car. The trunk could be a little deeper (48") for three sets of golf clubs.
