I am a route salesman and I drive at least 28,000 miles a year.. I bought my Explorer in 2006 with 28k on it and just rolled over to 89k. The only problem I had was the back window stopped working but was fixed under warranty. I have driven through the Rockies in the snow, North Dakota, through mud, -30 temperatures and this Explorer has always got me home. Nealy 90k and perfect. My last Explorer in 98 gave me 260k. Just keep it serviced.
Good reliable 4.0 V6. moderate gas mileage. About 14.5 in town and 19-21 on highway. I drive hard though.. i have deadlines and need to meet themm, good stereo, comfortable seats, good michelin tires from factory.. 4WD woorks pretty well..
