MB CD is a waste of time? Your opinion or someone else's?
Where did you hear that the W140 manual will be available soon?
For my 95 S420, I toggle between an alldata.com subscription and the W124 CD manual set for the M119 (400E/E420). alldata provides clearer step-by-step instructions but navigation is a nightmare, line drawings are inadequate, wiring diagrams are arbitrarily cut into separate sheets and there are no special tool workarounds like Haynes manuals offer.
