Is this manual any good?
 

I've already got the Mercedes Bible for my w124, and I'm planning on buying the haynes. Is this "owners workshop manual" any good?

Better than most, still not as much info as the MBUSA CD on that chassis

From my understanding the Haynes is the best and it's lacking. I bought the actual Mercedes Factory Repair manuals (paper, not CD) from a company called TWC Publications. That sucker is is four inches thick and contains diagnosing things as well as all procedures for body, engine, and drivetrain. Possibly search this forum for their number, or I'll post it later when I get to the office - it's in my files.

I like the Haynes manual. It doesn't cover V8s, only fours, sixes and diesels. The CD is both thorough and brief, if that's possible. Haynes was pictures and generally goes into more detail. If you're really committed you get both of them.
