Bought the most expensive warranty they offered. To anyone but a mechanic, the list of covered items is exhaustive and appears all inclusive. I was sold on and bought the warranty in good faith under the impression that the engine, transmission, everything besides wiper blades, brakes, tires, etc. would be covered. Never thought I would have to worry about anything mechanical. Had two separate problems over the first two years. Both of which were not covered (despite the contract stating “all internal engine parts”) and both dealers saying “your warranty sucks” to me, identically. I paid almost $4000 for four years for peace of mind. Got totally ripped off.
