There are actually several versions of that book:
1) The German Edition: 160 Pages. #6510 1081 00
PLEASE VERIFY THE FOLLOWING, mine are not at hand.
2) The English Edition: 130 Pages.
3) The English Edition: 162 Pages.
The "long" English version is the rarest and the only one I do not have in my collection.
I believe that one should consider acquiring a collection of manuals as most are NLA. A complete "library" would consist of all the relevant manuals, plus a few general ones, for every car one owns (or plan on owning).
Some were produced, as far as I know, only in German. The more general type manuals, "Service," "Introduction to Service," "Electrical Troubleshooting Guide," "Preliminary," etc. were available in various languages.
Maybe I'm just an analog type guy but I prefer paper rather than pixels when it comes to manuals.
