Well that article doesn't go into how the claims are handled when you actually have a repair.
When I bought the contract for the Windstar above I had a similar experience as the article writer. My sales person called me out of the blue at home offered me a very high priced warranty for my "risky" high mileage Windstar , 50,000. When I wouldn't bite she lowered the price about $500 and added 1 year. When I didn't bite she put me on hold and a manager came on the phone and chopped $1,000 off the price to arrive at $3200.

I thought I was getting something good that would insure against a major repair... no such result. there's a sucker born evey minute. never again unless it is by the dealer selling me the used car.
