Car extended warranty?

Ford is offering me an extended warranty to pick up when my initial warranty ends, 5 years after purchase - which is next month. With a $100 deductible, it comes out to about $1300 over the three years of the plan; with a $250 deductible, it comes out to $972.

In the 5 years we've had this car so far, we've only had one repair that would be covered by warranty, $600. So it seems to me the odds are low that it'll need as much warranty-covered work in the next three years, as either plan costs. There is a chance it'll need something more expensive, but... that seems like a pretty low chance, doesn't it?

Also, they cover towing, and rental car in case the car is out of service for a short time. But we have AAA+ which covers towing, and my regular car insurance has rental car coverage.

Seems to me that it's not worth getting the extended warranty. Opinions?
