I purchased my Warrantech extended warranty from an independent garage that sells/services used Mercedes. I priced the exact same Warrantech warranty at the local MB dealership and it was 30% more expensive. I can still take the car almost anywhere to have it serviced including the MB dealership.
Warrantech will not deal directly with the public and has refused to tell me who offers their warranties. I called their 1-800-328-2655 today and spoke with customer service. Basically they said to call "all of the dealerships and garages in your area" to find out who offers Warrantech. Thankfully, their claims payment is much simpler!
