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!

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!!!

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
