I love my X5M as a daily driver. I wouldn't want anything else. I pretty much have every option except for rear dvd, rear AC, and smartphone integration, none of which I felt I needed. All the other options are great. And I also agree that the comfort doors, only $600 more on an already $90k vehicle, are definitely worth it.
The multi contour vented seats are so comfortable too. Every passenger who has ridden in my car agrees that these seats are one of the most comfortable seats they have sat in.
Only negatives about using it as a daily driver: gas mileage as posted before and careless people putting scratches, dents etc on the car. A friend was loading groceries into the trunk yesterday and accidentally hit the bottom half of the hatch with a wine bottle and left a small dent.
