I paid for mine today. It will be here sometime between Tues and Thur this coming week. Got the paperwork done and signed today. They are letting me drive my current I'm trading in until my ride gets here in a few days.
As for the warranty, I paid 4k and put it into the loan. However, that covers everything for 6 years instead of the standard 3 plus bumper to bumper; any maintenance such as brake pads, oil changes, filters, shocks, etc; full tire coverage, any dings or dents for whatever reason up to 4" (anything past that will need to be covered by insurance), windshield cracks, a loaner vehicle anytime mine is at Ford for whatever reason, etc.) and there is no deductible on any of it. I did the math and as many said, to extend to 6 years is about 2k by itself for the bumper to bumper. Throw in synthetic oil changes for 6 years and you're around another 1800. One door ding and you're in the black plus anything else.
FYI, I usually don't go with extended or maintenance packages since I don't keep them that long usually. This one will be a keeper I figure and even if I don't, they will reimburse a pro rated amount of the balance of time remaining on the warranty.
