The GL is a perfectly sized SUV. It is large enough to carry 6 people comfortably yet not so big that it looks like a behemoth coming down the road. Its size makes it very maneuverable and easy to drive for such a large vehicle. The GL320 Bluetec uses approximately 30% less fuel and polutes 30% less than other large SUVs. 500 miles in the city and 600 miles on the freeway are the normal fillup intervals. On the freeway, it handles better than most sedans. The steering is not loose but at the same time isn't so tight that the vehicle swerves every time you adjust the HVAC. The rearview mirrors were made larger in 2009. Any larger and they would look out of proportion to the vehicle.
Very disappointting!!! for those of you guys who are seeking the good ole fashion quality of the benz a word of advise SHY AWAY. The 4x4 of the year can not sustain a small bump from the side walk curve without busting its air- suspension module. Interestingly enough, when taking the vehicle to the local benz dealership the Service manager told me, " hey this car is just like a kia and a hyundai, what do you expect, its build the same" I was floored by the lack of cooperation and needless to say the poor craftsmanship. If I wanted a kia i would buy one, well, maybe i should have. It is a shame that a 70K+ 4X4 of the year is basically a kia with a mercedes star on it.
I have owned too many suvs and trucks to mention. This one is the very best. Fuel Economy is much better than advertised. Driving in Phx I get 23 in town and 28 on the highway. Great design and build quality. I pull a large tent trailer with a gross of 5,000lbs with no problem. I will be going "long" on this one. Also, it is fun to drive. Everything is well layed out. So far 7,800 miles without a single problem, nothing.
I have this vehicle for over 2 months and stumbled into a common mistake and filled up with gas. Costing around $800 to remove the gas when I did not started the car and realize while fueling. If you start it may cost you $6000-$8000. Very delicate fuel and exhaust system.
Finally a solid, high quality, 7 passenger AWD SUV with the looks, comfort, quality, and features that we have been looking for. Actually drives better than the gas version (more torque) and gets 21 average; 26 highway. Very smooth and quiet; no one can tell it's a diesel.
