My wife and I loved this car!! It was primarily my wife's everyday ride. The diesel was peppy and economical, although Mercedes-Benz has had some oil and turbo issues with its Bluetec engines due to engineering compromises made to meet unrealistic California emissions rules. This car would haul 13 bales of pine straw in the morning and, after a quick sweep, be an elegant ride to a dressy dinner that evening. Great on long road trips or around town, and the 115V outlet meant the blender went with us on tailgating Saturdays. Very comfortable for me, a 5'6" geezer, but equally so for my considerably taller and decades-younger wife.
Never buy a Mercedes. They are not reliable mechanically. The SUV spent more time in the shop than on the road. Diesels are not the way to go because you will have to replace the DPF filter at a cost of 4500 to 6500 dollars. Short trips the kill the DPF filter faster. That is almost half the value of the SUV. Mercedes should be sued for allowing this piece of junk on the road. I will never own another Mercedes again. The diesel engine which you can Google and read about is junk. The engine is an OM642. The engine oil is 10 dollars a quart and it drinks it at a rate of 1 quart every 1500 miles. Do the math on that one. The urea tank heater will fail which is 1500 dollars. I think it is also a bad great idea to not have a spare tire either and no place to put one.
