Our car is the SLK320 (R170) but I believe the C320 has the same pump. The MB part number I posted is the correct part. As far a a rebuilt part I am sure there are several rebuilders and the R170 platform started using the M112 engine about 2000 I believe, for a aftermarket pump just look for a SLK320 (R170) with a M112 engine.
