I currently drive a 2008 ML320CDI and in terms of fuel economy it performs very well in my opinion. The figures of 18/24 are pretty accurate, though it really depends on your driving.
After buying the car in December I took it on a road trip to New York where I got about 24.3mpg max even though I drove 80mph average but was very soft on the pedal. However, about 2 weeks ago the mileage on the car went up and I now get around 24 minimum on the highway and up to 27 if I drive it well.
For the city, I have only ever gotten 17mpgs if I drove the car quite hard (fast acceleration etc), but usually I never go below 18 and average about 20-22/23 mpgs in the city. Generally even if you're getting about 22mpgs on the highway or whatever, the car will usually average 20-23mpgs city and highway driving if you drive it normally. The mileage does go up now quite quickly when I drive it steadily over prolonged distances (it went up by 3mpgs from 21.5-24.5 after having spent about 2 minutes doing 65-70mph on the highway after city driving). My car is currently hovering around about 4,000 miles driven. I'd say at about 3,500-4,000 miles the engine should be worn in enough and you'll get those higher mpgs.
In any case i've had no problems and the car has been absolutely joyous and lovely to drive. Definitely a great purchase and it gets quite a lot of looks, and when you compare it to a lot of real-world mileage of gasoline SUVs it does quite well. Diesel prices don't matter as much to me, as the higher mpgs for an SUV and the 25.1mpg fuel tank make up for it. That, and the fact that diesel stations are actually easier to find than most people think, and if you look a bit longer you might find cheaper diesel rates down the road. I doubt diesel prices will go sky-high and when you consider the greater efficiency of diesel and the coming of diesel vehicles by VW, BMW, Audi and the Japanese as well as new Mercedes models, its worth it.

I've got an 07 ML320 CDI and I also get stunning MPG. On a recent long trip to Cape Cod with a loaded SUV I got 26.5 and that was doing near 80, I divided gallons used into total trip miles when filling up.
In winter Diesel is higher but in summer it is much lower, less then regular in some cases. Keep in mind Diesel in winter is around the same price (maybe a little more) for premium which all MBs require. Bottom line, with the extra miles you can go on a gallon and low summer prices you are paying less overall for Diesel. Get one...oh and that torque is intoxicating

It is something that has to be experienced. You can have the gassers HP, I will take the diesel torque any day. How do you like the 7 speed transmission?

The 7 speed is ok but I do get a couple shift kicks if I do strong acceleration and then let off the gas, the tranny wants to go for the high gears ASAP so it will jump 2 to 3 gears if you let it and gives you a double kick. Only happens if I am aggressive then let off the gas (reaching 40 or so). Of course this could be because of the bigger torque causing a snap as I have a CLK with the same 7 speed and do not notice this.
I finally found a use for the shift paddles on the wheel. The ML diesel loves to engine brake going down hill or stay in the best RPMs for full torque at lower speeds (gear 4 to 6 at 30 to 40) - to get better MPG I force it to stay in the highest gear with a tap of the right paddle....works fine. I will add that auto engine braking when coming to a full stop is great benefit - love that subtle growl too.

Thanks for all your replys. PS I pitted 3 dealers against each other and saved another grand plus got them to throw in running boards..

Help, I just filled up my new 08 diesel with low sulfur and not ultra low sulfur. Should I pump it out? should I just fill in more of the correct ultra low? HELP HELP!!!

My ride is so new I have not even fueled it yet. Hit your teleaid info button and choose vehicle information when they ask and they will have your answer in minutes while you sit in the car. Let me know what they say.

Pump it out! You could seriously mess up your ride if you run it on Low Sulfur Diesel. From what i've heard it'll emit black smoke and u'll hear the engine chug followed by the engine potentially breaking.
Low sulfur has 550pm and Ultra-Low sulfur has 15ppm so you see the difference.
I haven't filled with low sulfur yet cos i'm really careful not to- don't wanna risk damaging the engine and I think you definitely shouldn't try to run on low sulfur.

I asked my salesmen and he said it's a new car and it's ok, but don't make the mistake too often. I was hoping anybody have more information. Somebody like a mechanic or similar profession.

What I've heard is it can clog the special exhaust system, MB will not warranty it if that happens. The system is $1500 or more. those 550ppm and 15ppm numbers mean parts per million, so imagine 550 particles getting filtered through your exhaust system all at once vs 15 particles - not wholly accurate but you get the idea.
You may be ok as it is a new car and the system is clean...but go ahead and get the ultra low in there to start and dilute
