04 E500 have almost a million miles on Diesels, but this car is something else. Was at the dealership for oil change, they noticed a little oil leak from driver's side of engine, valve cover, fixed them both, evidently a problem with this engine. Other than that, get at least 25-26 mpg, and it handles like a dream.
