A car's life isn't determined by miles driven.
Mileage is just one indicator of a vehicle condition. Theoretically, a vehicle that has covered more miles has more wear and tear, but a car with 60,000 miles on the odometer can easily be in worse shape than one with 120,000 miles. Cars and trucks like to be driven.
Why does used car mileage matter? Every mile you drive contributes to the wear and tear of a car, so mileage can act as a rough estimate of a car's longevity. Under normal circumstances, a vehicle with 40,000 miles may be considered relatively new, even if it's several years old.
