It's important to remember she bought this car from a dealer, and it was 8 years ago, when the car was "only" nine years old, not 17. Generally, people who buy cars from dealers expect peace of mind and few problems in exchange for paying a premium for the car in question. I'd be a bit upset too if I bought a car from the dealer and it immediately started having the problems this woman experienced.
In fact, if you browse copart, you'll see "franchise trade-in" cars being sold at auction there. These are cars that the dealer has received in trade and does not want to stand behind -- they just want to take their money and leave the problems (and they probably know it has a serious issue) to you. It's an easy way out of liability for them.
All that being said, it was rather foolish of her to buy a car without a sufficient warranty for her needs (or if it did have a warranty, it was really foolish of her to not stick the dealer with the cost of repairs.)
