I assume that MBZ does not make all the parts that go on the car. I am also assuming that it is a lot better made than the water pumps on US cars that tend to last about 70K miles.
Repairing water pumbs is a lot harder with the serpentine belts and so forth used these days. It took me about three hours to replace the one on my 77 Toyota Celica. I imagine an experienced mechanic could do this in under an hour.
