8. 1966 Mercedes-Benz 250SE – 1.2 Million Miles
This heavy-duty pickup, owned by Hugh and Tammy Pennington, has reached the milestone of 1 million miles, a feat often seen in rugged work trucks.
The Penningtons credit the truck’s longevity to meticulous maintenance, including regular oil changes every 5,000 miles and thorough cleaning to prevent corrosion from snowy and salted roads. Their dedication has kept this Silverado running strong despite the harsh conditions it regularly faces.
