When I bought my '04 XF about 3 weeks ago, I purchased from my Chrysler dealer a Chrysler 5 year or 50K mile (from the date of my purchase) extended, bumper to bumper warranty. It covers the powertrain and 5,007 parts (everything but wear items, brakes, rotors, etc. - a very short list of what's not covered. I have similar coverage on my Sebring Convertible and Pacifica. They always give me a free loaner car if the repairs take more than one day. If it's for a day, I give Enterprise their $35 for the rental (has only happened once). They are supposed to charge me a $100 deductible for each visit but that has never happened in the past 2 years! Don't tell anybody. Before anyone asks, the dealerships have a lot (LOT) of latitude on what they charge for the warranties. Basically, I told them what I would pay for the car, tax, title, tags, and extended warranty and let them figure it out. I don't really car how they write up the sales invoice as long as the bottom line number is my number. Roughly I would count on spending between $1,600 and $2,500. I couple of repairs in 5/50 takes care of that number. Best part is, I don't care what is broken, just fix it. With a check engine light on they can tell you it was caused by anything; it could cost $100 or $1,000. I don't care, it had just better not be on when I pick up my car. In 2 years, my total costs for the other 2 cars has been one rental ($35) and $5 for a fuse. End of my story.
