When buying a used car, a common debate is whether mileage or age matters more. While both factors are important, mileage often provides a clearer picture of a vehicle's condition. A car with low mileage but high age may suffer from dry rot, rust, and deteriorated seals due to lack of use. Conversely, a high-mileage but newer car might have been well-maintained and still have plenty of life left. The key is to consider the car’s maintenance history and overall condition rather than focusing solely on one metric. This video from Autotrader explains how to weigh miles versus age to make a smarter purchase.
