All warranty contracts are not created equally! Believe it or not, your MB dealer may be the best source of information concerning after-market warranty contracts. Ask your service advisor for some advice. The SA's the ones who deal with these issues day in and day out.

Warranty people don't pay what repair centers charge. Plain and simple. Their database can be WAY out of date. But they are better than no warranty, especially with cars as unreliable as MLs. Things to ask about are :

deductables (can be high, and you have to pay on every visit for the same problem)
percentage of parts price covered. I would propose scenarios, such as compare what they'd pay for a new AC compressor or tranny, etc, and then ask the dealer
standard labor allocation: check their proposed labor vs dealer (e.g. is it 1 hr or 0.7 hours for a given task)
try calling their service number and pose as a repair center instead of a customer. sometimes they are REALLY slow.
service records: read the fine print on how your car has to be maintained and documented
