I bought our Expedition used in 03 with 70,000 miles. It has been a fantastic vehicle for us. The versatility of taking eight people or hauling things has been great. It has just the 4.6 engine and I have put it though the mill. We haul a 5,500 lbs camper around each summer and I have a piano service business and move pianos all over the midwest in a 3,000 lbs enclosed trailer. This old girl now has 190,000 miles with no major breakdowns. It was our main family vehicle for 5 years and we couldn't have been happier with it.
Reliable, comfortable ride, versatility, looks great, the rear AC was awesome, turning radius. I always got about 17 mpg (about 9-10 with the trailers) but I wouldn't be driving a truck if I was concerned about gas mileage. 17 was pretty good.
Child locks always turned on by themselves. Sometimes transmission wouldn't downshift when towing uphill. CD Changer quit working.
