 We purchased this one (our 3rd Expedition) new in March or 2003 and broke it in on a road trip to Mesa Verde.  The literature indicated that it would get only 13 mpg or so, but by keeping our speed around 60 mph we have averaged over 18 mpg overall and over 23 mpg on one trip from Fontenelle, Wyoming to Denver. I am tall (6'5") and this is the most comfortable vehicle I have owned.  It is so nice to have a car that actually fits me.  It has all of the comfort features one could want and the heated and cooled seats are a real treat.  We haven't had any problems at all and I expect it to last at least another 10 years or more.  Great job Ford!
