Ford may sell extended warranty but they often are not backed by Ford. Commonly a third party insurance company there. Once I bought a Tempo back when I was still unsure of my skills at repairing new car electronics. The extended warranty was $980 around 1991 or so, again third party co. The standard warranty back then was 3/36000 and I got the extended warranty card in about a week, it covered up to 75K and 3 more I think. Anyway, got a Ford branded warranty card about 2 months+ later and upon looking at it realized the warranty there was virtually exactly overlaying the extended one I bought, but this one was mentioning another plan I'd not heard of. In short, as second owner of the car I was entitled to another 3/36000 extension for $100 through Ford themselves, they didn't mention it at all and instead added the $980 one that had virtually same coverage and bigger deductible. I found the $100 option in very small print on sale paperwork. Realizing I got taken, went to dealership and surprised they didn't have police escort me out. I accused them of ripping me off and got a refund, but since just past the two month limit, I lost the option for 100% refund, getting back only $780. Here's the kicker. That was maybe 2 months before the implosion of the economy through 1992, the insurance company that underwrote the warranty was one of the ones involved in the Orange County, California pension fund fiasco and when it went belly up the warranty company did as well, rendering all warranties sold under that company instantly null and void. I just missed it and was very thankful. There were shops all over the DFW metroplex that got taken for many thousands of dollars in warranty work performed that no one could pay for, as well as private vehicle warranty holders that suddenly had worthless warranties bought and paid for. Real big news story at the time. Later on I discovered upon reading the fine print in warranty they did not pay for any high tech, you had to buy the 'hi-tech' option, of course not shown to me either and ANOTHER $500. Or, the warranty I had covered nothing I couldn't fix on my own.
That was the first and only warranty I've ever paid for ever. Now I laugh at them, when they ask how I will fix my car if something I cannot understand goes bad I laugh even harder. It really pisses them off at new car sale time, they cannot sell me anything other than car itself, and I never tradein to let them get me there either. Looking back, there is no way those expensive warranties ever come close to paying off except for those who absolutely detest working on cars. Doing all work myself generally has me not paying $1000 total for parts on any car I've ever had throughout its' total lifespan, and most are way less than that.
Certainly one end of the extremes, but it can be done.
