Apples and oranges being tossed around here. Aftermarket company warranties are totally useless and not worth the paper they are written on. These companies are famous for splitting hairs and writing contracts that get them out of 75% of repairs. Their next line of defense is to just go out of business (change names) every few years, leaving any current policy owners out of luck.
Factory backed warranties (called service contracts in most states) are a whole different beast. They are a rip-off when bought in the cubicle at the time of purchase for the price first offered. But they can pay off if you keep the vehicle for a long time and don't plan on doing a bunch of "mods" that void the warranty. They are good for repair at any dealer and are the way to go if you want to get a warranty. And if you purchase a factory warranty, shop the price online. You can buy from any dealer in the US (or beyond?). I paid $2200 to a dealer over 1000 miles away from me for a warranty that my selling scumbag dealer was offering me for over $4,000
It is true that in the long run a warranty is a bad bet but if you're the rare guy that has a tranny or engine failure you don't care that the other 999 guys didn't have it happen to them.
