I have been consulting and comparing the Mercedes 124 FSM and the Haynes 124 manual while going through this same process. I have found that the FSM is a great source for the information, accurate and complete, but difficult to navigate as you have to move from section to section chasing the various procedures. The Haynes manual has not yet had an omission nor disparity.

I suggest both: The FSM for your desk, I print pages for a binder in the garage as I work, and the Haynes for the garage for quick reference (torques etc.).
