||Head of Service department at the Mercedes dealer told me not to buy it, didn't pay what they should, forced them to utilize used parts, etc, as has been echoed by posts above. This even though the policy was sold through the M.B. dealership! Had not purchased it yet, then came across this string, just in time.
Their flyer says they are a member of the BBB (Better Business Bureau). Plugged in their name, and many variants of how it could be listed....never showed up on the BBB screen. Will look for alternative after market warranty coverage. Thanks for the heads up all!
