This person seem to carry just about all the shop/repair manuals for all makes of Mercedes and other cars. However, I dont know how extensive and/or good they are. Just go to the following item on Ebay and ask him through an email whether he carries your W140 manual.
i think if you look at what he is selling they are copied CD's. he notes in the last line of the ad that the material is from a 3rd party.
