Yeah, I still get those, too. The one I liked best was the one that said it was better because it would cover me all the way to 125,000 miles! And here I am with 125,610 miles on my no problems Sport Trac.
If you need them, they can be a great help, or make it even worse. Just make sure you know what you are getting for your money. They can be very tricky with their words. A friend put his explorer in the shop for a new transmission once, and wound up with a used transmission from the dealership, and still had to pay the deductible and the rental car he thought was covered! The warranty people argued with the dealership for a week about how much they would pay, all the while the dealership was building up rental fees.
Personally, I think you would be better served to put the money in the bank, to be used if you need it. The warranty people have run the numbers, and they come out ahead if you buy the policy. Chances are you won't ever need it. If you have the money in the bank, you still have your money if you don't need repairs.
