Scott...I saw a vaccum pump going for 325.00 on eBay for a w140. Thats not exactly cheap, but its a heck of alot cheaper than getting it from the dealer.

I go into eBay on a daily basis and do a search using "w140" in the search field. Brings up most of the items that will fit my S320. You can also try "mercedes pump" or something similar.

good luck.
