Interesting. What do you ever do to an engine that requires a manual but not torque specs?
Hardcopies of MB shop manuals are available on ebay from time to time. MB CDs are also available but you can't tell bootleg from original up front.
The nice thing about the CD set is that when you wise up and get a Diesel

you don't need a new set of manuals.
