My wife's car. Wonderful for her - sits high with great visability & comfort. The AWD is supurb here in Denver - great in snow and it doesn't eat up tires as I feared it would (we get 40K miles per set). Gets only 20 MPG on highway at 75. (I don't even try to determine our mileage in the city!) Reliability has been better than some other owners reported: Replaced air mass sensor (expensive!) at 55K miles (it caused transmission to shift late or not at all). Replaced front brakes at 40K and 73K; rear brakes at 73K. Brakes/rotors are expensive, but very, very easy for a do-it-yourself project. (Brake parts for four wheels cost me about $350.) Transmission can't be serviced by non-MB shop.
Great low-range gearing for negotiating steep, rocky trailheads in the mountains! Excellent ground clearance and short wheelbase make back-country driving easy.
Better warranty. There are too many expensive repair situations where owners are greatly exposed to unexpected budget busters!
