I bought two manuals on eBay ($110).

Service Manual
Chassis and Body
Model 126, Volume 1

and Volume 2

I recognized the pages from the MB W126 CD I had bought earlier (crappy scanned version).

Difference is I can read these very clearly and I can thumb through the relevant pages at the car, rather than going back inside to the computer (laptop really doesn't cut it either).

Best $110 I've spent. Not sure if there are other volumes, but these two are great!
