Determining the precise impact of mileage on price differences can be challenging. Several factors, including changes in the license plates, regulations, and overall wear-and-tear, all contribute to the depreciation of a car’s value.

Generally, an increase in mileage results in a decrease in value. Roughly, for every 20,000 miles added to the total mileage, one can anticipate a roughly 20% reduction in the vehicle’s market value due to perceived wear-and-tear.

This depreciation rate may be higher for older vehicles with substantial mileage.

Furthermore, vehicles with lower mileage may still have the benefit of being under the manufacturer’s warranty, offering buyers additional reassurance. 

However, for vintage and classic cars, high mileage does not always equate to lower value.
