Extended warranty. What are your thoughts

Remember that the dealer doesn't pay that much for a warranty so you can dicker with him until he just wont go any lower. The last time I bought a auto makers warranty, they started out at $2800. I told them I'd pay $1k and after lots of going back and forth, he finally sold it to me for that price. He then told me they only pay $800 so anything over that is gravy.
BTW, it was a total waste of money - never used it.
Haven't bought one since.
