I have owned this car over 10 years and it has been a pleasure to own. Pretty simple compared to new cars but a very reliable vehicle with many good years left. I would not hesitate to buy one this age with high miles. My wife says it is time to sell. She just wants something new with a little more horsepower! The suspension seemed a little soft after 10 years so I put new Bilstein shocks and springs under it to improve the handling. I had new bearings put in the all wheel drive unit that Mercedes always denied having an issue with. Mercedes fix is a new $4500 unit. You can buy the bearings for about $300 and a mechanic can do the repair in less than a half day. I like the 2008 because it is the 48 state engine without the urea addition that resulted in the run flat tires in 2009.

I ordered this car with all available options. Towing my horses on highways and hills is effortless and I have NEVER gotten less than 20mpg. I find the nav system very accurate but data entry is a pain. The Airmatic suspension makes a HUGE difference in the ride and handling quality over lesser-equipped M Class cars. There have been zero defects, so my only expense has been to replace the tires and 3 maintenance stops. An outstanding vehicle made in the USA!
Good SUV

Bought this vehicle new and have been impressed with the handling and the fuel mileage. No one even guesses that this is a diesel when they are riding in it. One of the best features is the locomotive like pull while merging onto the interstate. Absolutely no problems finding diesel and with the large tank you cover a lot of distance. 27mpg in mixed driving.
Best SUV I have ever driven!

Have had the car for couple of months now. Great power under the hood - the turbo really makes a difference. The fuel economy is excellent. Once you get the hang of it you can get about 32MPG highway and about 20 city - I get about 25-26MPG for 50-50 city/highway. Not bad for an SUV with this size an power. Can't mention enough about the torque! All in all the best SUV I have driven (compared to Lexus, BMW models). Have taken it to the mountains - starts with ease and pure pleasure to drive up hill - gasoline engines are no match to the power!!!
An excellent SUV combines the goodness

I own a Toyota minivan. I have tried Lexus Rx and GX 470, BMW X5, Toyota 4-RUnnner and Highlander hybrids before I settle down to this ML 320 CDI. All the Toyotas and Lexuss have the similar driving trait and characteristic, includ quiet, comfort but boring. BMW is impressive for its road handling and driving capability but it is louder and coarse. Its electronics is too complicated with a lots of trouble. The Mercedes combined all those goodness plus the advantage for fuel economy. So far I got 22-24 MPG combine local and highway in the break in period. The truck is more comfort and quieter than Lexuss and Toyotas. The road handling and drivability is definitely better than Lexus and Toyota
Nice car but many little problems.

The dealership is excellent and does its best, but my car had a battery drain problem that left me stranded in airport parking lots several times after long trips from Europe and Asia. After many interventions and, as long as a week at the dealership at a time, to check it out, they changed the battery. I suspect once the battery gets old it will discharge again but I only have a few months left on the lease. The car also has had small problems that should not appear on a 55K plus car.
A good Mercedes Diesel

SUV is more than we expected. Good driving experience, excellent mileage @ 30 mpg highway and 25 in town. Radio and MB tech pkg helpful. HD lights a must, XM radio and NAV work well. Seats comfortable even with MB Tex. Would definitely buy again. No problems so far in this nearly 2-year- old MB Diesel SUV. Bought the extended warranty to 100K miles.
Love my Mercedes M Class Turbo Diesel

Sold my '03 BMW X5 and purchased my ML 320CDI in Jan '08. I was torn between the Mercedes and the new BMW X5 but chose the ML based on good looks, power and fun to drive. I find I just want to get in the car and drive. The SUV is smooth, quiet, luxurious and most of all great fun to drive. Terrific sound system. Average 22 mpg combined city/highway. No problems since I purchased it. Would highly recommend.
Better looking than 2009 model

Love the car. Got it a week ago and I'm most impressed with the power under the hood. It's like taking off in an airplane, you just don't feel the transmission shifting. I took it on a 600 km trip and performed with "flying" colors in the fuel consumption department.
Why do hybrids even exist?

Wonderful vehicle. Terrific performance from all that diesel torque, yet it gets superb mileage (avg. 22.1 MPG over 45,000 miles). Very comfortable on long trips. Lots of storage. However, it's outrageous that memory seats are not standard equipment at this price. Maybe they are now standard on newer models? My dealer in Grand Rapids, Michigan is excellent, both sales and service. BTW, hybrids are a losing proposition. We already have diesel infrastructure in place, the technology is proven beyond a shadow of a doubt and the diesel complaints (noise, polution and smell) have been solved. My second M-B diesel won't be my last.
