Great it worked out for you. I agree with you unless your one of the lucky ones who go problem free for the entirety of the ownership. In today's world with the complexities of our automobiles it has become a must have for me to have warranties for as long as possible and as all encompassing as possible. Labor rates running over $150. an hour and parts costing crazy amounts means it doesn't take much of a problem to begin to see the added cost of a warranty pay for it self.
The only caveat I would add is if your not going to have the car more than a couple of years i can see not doing it but many of those warranties are refundable if they are not used. You won't get back all your costs but many times you will see a refund of several hundred dollars assuming you have not utilized the warranty.
Also I would encourage anyone to make sure you bring that up if you are trading your car to a dealer or selling it . In my experience the dealers may not let you know that when you trade your car in. I I didn't realize that there could be money coming back to me until a few years ago when i stumbled on it by accident. Hate to think how many times over my lifetime i failed realize I had money due and just went on without completing the steps to get my refund . It requires you to have documentation from the purchase along with proof of purchase , such as credit card receipt or cancelled check or contract showing payment but if your able to find it years later it mean several hundred dollars in your hand as it did for me.
