Good evening,
After falling down a rabbit hole last night, I found some PDF's of some various 1980's owner's manuals for the USA/Canada market. Here's the ones for the 1981 - 1989 S class. Not one for every single model/model year, of course not ever model year had changes.
These are the ones for the Sedan and coupe models.
Here you go.
