extended warranties are a tough call. In the long run it is almost certain that if you put that money into a bank account and forget about it you'll make out better.
On the other hand, if you have all your receipts, saying "look i don't effin care, you deal with it" is handy..
I had a Chrysler extended warranty on my '95 intrepid; never needed it.
I had a "warranty gold" warranty on my '99 Durango. I don't think I ever needed it. Warranty Gold went under, and I did get a small check from the settlement.
I had a Chrysler extended warranty on my '03 durango. Inner tie-rod end failed. Dealer made a stink about replacing it. Chrysler dealt with it.
My 07 WK has the limited lifetime powertrain warranty, but I bought the aftermarket 5/100 add on that the dealer was selling. Never used it, beyond 5 years now.
My advice is that an extended warranty is on the edge of "maybe, maybe not" .. but after all my experiences I'd get a Chrysler warranty, just because there's less jerking around at the dealer getting something fixed, and adding a third party into the mix just makes things more difficult. There are many Chrysler dealers online that sell these warranties for a good price if your selling dealer won't play ball.
Why do I say "dealer"? .. hm, well, based on (painful) experience, when you go to the local highly recommended independent to get your leaking front differential pinion seal replaced, you will find that this is not something they learned how to do while fixing toyota corollas and honda civics
just my $0.02
