We have had our '97 Explorer XLT AWD V8 since new and it's now 12 years old and has 169,000 miles. This is by far the longest we ever have kept a car both in terms of time as well as miles driven. This truck just keeps on going. We use it every day from mundane things like commuting to/from work to bigger things like camping vacations, driving trips and trailering loads. No major repairs in its history - just the usual things like battery, brakes, and tires.
Power and reliability of the 5.0 V8. We bought this truck new because it had the 5.0 V8 and have not been disappointed in our choice. The Explorer's size and comfort are a close second - it fits our family of 4 and all of our stuff perfectly when we go on our camping trips.
