7: 1991 Chevy Silverado
The CK series GM trucks are among the most popular pickup truck models of all-time. Frank Oresnik managed to get his Silverado over the million-mile mark while being interviewed by NPR. “This afternoon, somewhere between Chicago and Shawano(ph), Wisconsin, Frank Oresnik reached a milestone. His truck reached the milestone. It’s a 1991 Chevy Silverado he drives it delivering steaks and seafood north from Chicago. And, today, Frank Oresnik’s odometer approached one million miles.” – via NPR

The fact that the Silverado made it over a million miles is a true testament to the fact that routine maintenance is key. The GM 350 V8 is one of the most well-respected engines on the road, and with proper care, you can get a lot of life out of this engine. Needless to say, Oresnik is still driving his Silverado to this day.
