That is a Toyota, mscher. With only 100K on her she is just broken in.
I bought an extended warranty on an Olds Diesel back in the 80s. It was so bad that the insurance company paid me blue book retail just to let them out of the contract. That one was a good investment.
Bought a 100K extended warranty on a Mercedes ML in '04. Never had even the smallest claim. Waste of bux.
Given that Toyotas are the most reliable machines on the planet (according to daughter #3, who has four and according to Consumer Reports) I would not expect a further extended warranty to pay for itself. I certainly wouldn't buy one on my Subaru Forester. Daughters #1 and #2 both have Subies that are over 150K and still never break.
Now if you had a Chrysler/Jeep product. . . .
