Extended warranties are not sold to you because the maintenance companies like you and care about you. They are sold because they are monster money makers.
Bank the cash you would spend on premiums and you will be able to pay for your repairs out of pocket and if nothing goes wrong, more likely then you win big.
Normally I would agree with you, but considering the issues I had during my normal 3/36000 warranty, I bought my extended warranty just before the base expired. It more than paid for itself. Probably 2-3 fold actually.
It does not take much, like a tranny: boom, paid for itself right there.
I would never buy an aftermarket warranty.
