There's no single "good" mileage number for a used car, as it depends heavily on the vehicle's age, maintenance history, and type. A better metric is the average annual mileage, which is around 12,000 miles. A car that's consistently below this average is generally a good sign. For example, a 5-year-old car with 60,000 miles is right at the average and often a solid bet, whereas a 2-year-old car with 50,000 miles has seen heavy use.
The most critical factor isn't the number on the odometer but the proof of consistent maintenance. A well-maintained car with 120,000 miles can be a much better purchase than a neglected one with 60,000 miles. Look for a detailed service history with records of oil changes, tire rotations, and scheduled services.
Here’s a quick reference table for mileage by age, but remember these are just guidelines:
| Vehicle Age (Years) | Excellent Mileage | Good/Average Mileage | High Mileage | Critical Checkpoints |
|---|
| 3 | Under 30,000 | 30,000 - 40,000 | Over 45,000 | Check for remaining factory warranty. |
| 5 | Under 50,000 | 50,000 - 70,000 | Over 80,000 | Major 60k-mile service interval due. |
| 7 | Under 70,000 | 70,000 - 90,000 | Over 100,000 | Timing belt and transmission fluid often due. |
| 10 | Under 100,000 | 100,000 - 130,000 | Over 140,000 | Inspect suspension, exhaust, and potential rust. |
Also, consider the vehicle's purpose. A highway-dominated 100,000 miles is typically less stressful on a car than 50,000 miles of constant stop-and-go city driving. Diesel trucks and certain models known for reliability, like many from Toyota and Honda, can often comfortably exceed 200,000 miles with proper care. Ultimately, a pre-purchase inspection by a trusted mechanic is the best way to validate any mileage figure.
