Its a DVD, not great, but good from MB literature, has been available for about 5 years, a hundred or so.

I think Performance products also sells the MB version. The other option is to buy a "All Data " subscription, nothing else good out there.
The 140 covers all 140 years, along with service bulletins, and electrical diagrams. To tell the truth, they are the most confusing diagrams, and I spent 4 years in electronics school, and 10 years in the factory reading schematics.
