The mileage that is considered good for a used car depends on various factors, including the make, model, maintenance history, and overall condition of the vehicle. In general, it's common for used cars to have an average annual mileage of around 12,000 to 15,000 miles. Therefore, a used car with approximately 60,000 to 75,000 miles could be considered good. However, it's important to remember that a well-maintained car with higher mileage can still provide reliable performance and longevity. Conducting a thorough inspection and obtaining a vehicle history report can provide valuable insights into the condition and maintenance of a used car.
