I bought the 2008 MB GL CDI used with 14K miles on it. I have 50K on it now. I bought 4 Blizzak snow tires for it and it makes it go through any conditions like a tank. I had the air suspension replaced under warranty by MB. No other problems. On a ski trip to Vermont one night got down to -10 degrees. Failed to start without putting in a bottle of 911 diesel fuel treatment. Started right up after that with no more problems. What a ride, 2 adults, 5 kids loaded to the hilt with a roof rack and still got 23 miles per gallon.
Solid, quiet confident ride. A true MB. Over 25 MPG on the highway with a full load, Amazing. I would take the diesel over the gas any day
I wish the second row bench would slide to give a little bit more leg room when no one was in the third row
