I have alldatadiy subecriptions for the SD and a couple of non-MBs. Navigation is unintuitive if you're used to the MB shop manuals or CD scans. Wiring diagrams are cut into screen size chunks making it really difficult to follow lines and words that cross pages. Images are generally much better than on MB CDs (you'd think MB could tear the sheets of a book for flat scans ). For things like pulling interior door panels, I find alldatadiy better than the MB CD. Note that I'm comparing the CD for a W126 vs alldatadiy for a W140. Could be the MB DVD for the W140 has the procedure spelled out in more detail.

Len, I won't get the book until I have a W210 I think BenzMac's is for sale (again) in the cars forum.
