2011 BMW X5 xDrive35d 4dr SUV AWD (3.0L 6cyl Turbodiesel 6A)
I also own an ML320 diesel (My wife drives the ML and I drive the X5) and although the ride of the X5 is not as smooth, the X5 is better handling, faster, and better fuel mileage (Averaging 24mpg in the first 1800 miles). I have only had the car for about 1 month, but it is a great car. I read reviews that the ride was rough, and the seats we not comfortable, but I do not find those true. The X5 rides great, and the seats are very comfortable. I do have the multi contour seats and you can adjust them in so many ways. My wife wants to trade cars now.
Radio, 20" wheels, seats, fuel economy, performance, and styling. iPhone connect is easy and great. Handsfree just became a whole lot easier. Rear air controls and sunshades, great for the kids.
