My current vehicle is a 92 Ford Explorer with 195,000 miles on it. I put 155,000 of those on it myself since 1996; it’s still running on the original engine with no rebuild. Previous was a ?90? Ford Aerostar (on loan from my sister-in-law) with 130,000, preceded in turn by an 84 Ford Bronco with 330,000 miles on it. The Bronco is still being driven by the guy I sold it to on the original engine, but I don’t know the current mileage; I don’t know the fate of the minivan, nor do I care.
The highest mileage on any vehicle I have personally driven is on a Ford Econoline box van that my family used for a delivery truck in our TV repair business. It averaged over 2000 miles per week, making pickups and deliveries all over Louisiana. As of the time it was retired due to irreparable body deterioration, it had over 770,000 miles on it. I believe it still had the original engine, with two rebuilds.
