Graf is good, at least 7 yrs ago when I had the 300D's replaced. Still OK, knock on wood.

For my C280, the water pump was going south almost at 2 yr intervals.(low mileage)
Last one I had replaced with a GRAF about 7 mos. ago.
We'll see how that holds out.

The Mercedes pump is about $400 for the C280.

Mercedes used to accept your old OEM pump as core and sell refurbished Merc pumps.

Probly not anymore... ???

I wonder if BARS leak tabs heavy duty, helps lubricate better to sustain life of bearing, esp. for the C280??
