I bought the vehicle new. 6 years and few problems. Oil sending unit did leak after 5 years. Didn't feel that should have happened. 48900 miles and still using original brake pads. Very surprised. Replaced switch for abs system. No other problems.Have changed oil every 10000 miles per fss.MBUSA insists on premium unleaded. I have burned regular unleaded for years. Can't tell any difference.
Enjoy the vehicle more and more through ownership. Comfortable seats. Fuel economy is excellent. Long trips average 23mpg at higher speeds. Test drove an 07'ML yesterday. It was a little softer ride but seats were not as comfortable as the 2000. Go figure.
Easier method of dropping the back seat which has been corrected with the '07, maybe earlier not sure.
