Great stuff in this thread. I took delivery of my Ltd last week so I've been looking into this a bit more. I looked at the Ziegler website and called Bob Cline whose name was mentioned in the thread. Had a good talk with Bob--no pressure, answered all of my questions, very knowledgeable. The thing that stood out in the conversation is that it isn't that expensive, at least right now, to wait to buy an extended warranty until you've driven the vehicle for a few years. He explained that under current pricing, if you buy a lifetime warranty after passing one year/12K miles, your cost is $170 higher (he might have said $150, not certain) than buying it in the first year. And, the same price differential applies right through four years/48K miles. They would still sell you a lifetime warranty for the same price differential relative to a first year purchase.
Obviously, prices and pricing structures can change over time--in fact, Bob said they usually get a price increase from Chrysler every two years--but I thought it was interesting that the price of buying later isn't much more than buying right out of the gate.
I told Bob I got his name and number from this thread and he says he's gotten a lot of calls that way!
