 If you are looking for a stylish, spacious, comfortable SUV with good highway mileage, this would be it! It took me six months to find this vehicle with the diesel engine and particular bells and whistles. We typically range between 24-28 mpg when we are on the highway using the cruise control, which happens to be one of the easiest cruise controls I have ever used, great design. My wife still thinks she is dreaming as the owner of this SUV and loves it more than any other car she has owned. Great space for sports equipment and plenty of passengers (the 9 yr. old loves his own back seat section with panorama moonroof). Now....the downsides! This vehicle was MB serviced by the previous two owners as if it was one of the family. Warranty up to 70,000 miles, when we bought it, and still runs like a top. On our 2nd long trip, only two weeks after buying it, the heating element for the AdBlu feature (Blutec) needed replacement, $1700 out the gate as the MB would not allow us to extend the warranty at the time of the repair, but the dealer gave us a small break on the price and tried to accommodate the situation. Servicing to do the brakes and for MB parts is not a cheap venture no matter what mechanic you use. Next issue was the air suspension, which we were warned about before purchasing. Front, driver side was "sagging" due to this malfunctioning and that part was $650 with labor we were about $1,000 with a very fair mechanic. I am sure the other side will go out at some point through normal wear and tear. Without the center knob to control the electronic components (phone, Nav., radio, etc.) like my other MB, this makes it very awkward to control and enter addresses. Very poor design on this component. Long and the short of it, we will bear through the expenses, diesel is cheaper for now, 20% more fuel efficient than gas, we expect to go many miles on this engine, good lines on the design and most importantly, the wife still loves it.
