Never believed in extended warranties. Always thought they were a waste of money.
I think you have to decide how you will be using your truck. If you are only towing 500 - 1,000 miles a year and then just some local driving, maybe you won't get your monies worth from an extended.
My truck miles are probably 80% towing a heavy fiver or more. I just figured I was really maxing my truck out to it's limits. I waited until the factory almost expired and then searched on-line and found an extended ESP Ford warranty from a dealer that was about 40% cheaper than my dealer.
But extended warranties are almost like an insurance policy, expensive and you may never need it.....but if you do?
