If you never thought an SUV was for you, add the 2009 MB 320 BlueTech diesel to your list because it handles very well, has lots of room inside, is safe, lots of TORQUE and is economical mileage-wise. I have observed 22 MPG city stop/go driving.With the most conservative driving style I've observed 30 MPG highway driving in an SUV not in an economy car! Be gentle on the throttle when pulling away from stop lights and use cruise control on the highway. The turning circle radius is good and the steering for tight parking is very easy to maneuver. The front and rear parktronic option is a must. The styling of the redesigned model is a huge improvement. Very masculine. Highly recommended

Since I do a lot of highway driving, at times in bad weather conditions, I feel I need a SUV. This MB beat my previous luxury Japanese SUV hands down, in terms of ride, braking, offroad (something the previous SUV just couldn't handle)and mileage. It sure cost more but the extra cost is worth it. Mileage is very good and one can't tell that it's a diesel engine. Using the cruise control significantly enhances mileage on highways. The transmission and engine deliver power smoothly. Diesel engines beat out hybrids when hauling heavy stuff and the ML320 has class-leading towing capacity. So far, no problems with reliability. Looks like MB has fixed the problems of the previous generation.

This has been a wonderful driving experience .The Diesel is very smooth and quiet and the highway milage is regularly over 28 mpg with average usually around 25 including city. The interior systems are fun and easy. The lift gate is great and at the right height to the ground and the space is more than ample.

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.
