For some reason I don't seem to be finding an owner's manual or shop manual for my new MB...

I see 350/450SL manuals are available but not for the S-Class.

Anyone out there with info, maybe a print of the 1973 Maintenance Schedule? Do these babies really take a valve adjustment?

I'm also looking for a replacement driver's interior door panel in tan, or any suggestions as to a way to repair a half dollar-sized cracked area (just where you would put your elbow). I'm also looking at a rear seat panel with a tear: it looks like www.************************ has all kinds of replacement seat upholstery for the W126 Series but I'm not finding a catalogue for ' 73-? S-Class. Would other year rear seat pads/covers, etc. fit?

Thanks in advance for any kind consideration!

p.s. Does 30+ years qualify as a "classic" in MB-dom?
