Electronic parts catalog, I think. It's the same system the parts guy at any MB dealer uses but the price list isn't current nor linked to a specific dealer's pricing system, obviously. You'll get the list and suggested retail price based on the either the 2001 or 2002 master price list. At least those are the masters I see in the EPC sets available. It's also a US-spec system so it won't recognize non US-spec, models, parts or VINs.
