Its been the least maintenance needy MB I've ever owned along with my W210 and brand new Metris....

Far less than the old ones.....Faaaaaaaaaaaaaaaaaaaaar less.

Its a blast to drive....369lbs of torque off the line just rockets it forward with ease. 30+mpg in a 4,400lb SUV

And it doesn't turn to rust-dust in the Michigan winter, always a nice bonus.

My normal annual servicing is adding some ad-blue....and an oil change, maybe an air filter/fuel filter if needed, which are super easy to replace.

Did the differential gear oil a while back, also not a big deal. I have the tool to force fluid up into the diff/tranny from below (for the front diff), and the rear one was the same as the old cars.
