Looking for a manual, found these

[cetilim]

Is anyone familiar with these manuals? I've been the Haynes and Chilton route already on other vehicles, and need something closer to the truth than those seem to be.

I found this one on Ebay:

I found this one at mercedesmanuals.com:

I have a 1992 300SD, and while I fixed a problem with the sunroof with no manual, I think the more ambitious tasks may require reference material, but I don't necessarily want to have to buy a library's worth of manuals to do it. Ideas?

Thanks.
