I bought the extended warranty with a 12 month payment plan @ 0% apr for my 2011 Edge Limited and my wife's 2011 Explorer Limited 4x4,( borrowing money for free is good). Also the complexity of the electronics is not what it used to be (Insync computer vs analog dials/gauges). I also agree it is like buying term life insurance, I dont want to use it, even if I have it. But if something does happen, I don't even have to rent a car. The warranty is the same length as the payment on the vehicles, 72 months, cash flow wise, repairs are hidden unitl the cars are paid for. We have already had a warranty claim on both vehicles, albiet within the standard 3 year warranty, fan on Explorer and AC duct control on Edge. So that's one less thing to worry about and I'm less likely to hate the cars before I've paid it off.
I also bought the ESP to cover maintenance in case a claim is denied by Ford because of lack of maintenance.
