We bought this 2000 Expedition new and now have 177K miles on it. All repairs have been wear related - alternator, upper & lower control arms (because ball joints are sealed and not replaceable separately), and the anti-lock control unit. I don't consider any of that major repair. (I had the original anti-lock control unit rebuilt, which was an inexpensive repair.) Of course we've done brakes, shocks, and plugs. This SUV rides and drives great and I will definitely miss it when I finally have to part with it. Only complaint is that it is under-braked, but I knew that when I bought it. You can run out of brake when towing in hot/high conditions - so beware when going downhill.
Ride, power (with the 5.4), room and reliability.
It needs larger brakes. Not sure if the newer version fixed that. Gas mileage is as expected in an SUV that big with a 5.4. We get around 14.5 mpg city/hwy even with 177K miles.
