How many miles is too many on a used car? What matters more than the odometer

Why the odometer is only part of the story

Two cars with the same mileage can be very different. One may have been serviced on schedule and driven mostly on highways; the other skipped oil changes and idled in stop-and-go traffic. Condition and care matter more than the raw number.

What to look at besides miles

• Service history. Regular oil changes and scheduled maintenance, with records, are the best sign.
• Age. A very old car with few miles can have dried-out rubber and seals. Very low miles on an old car are worth a question.
• How the miles were driven. Highway miles are generally easier on a car than short trips and heavy traffic.
• The model's reputation. Some models are known to last a long time; others are known for costly problems. Look up the specific model and engine.
• Condition. Wear on the seats, pedals and steering wheel should match the odometer.

Compare mileage to the average

Many drivers put roughly a certain number of miles on a car each year. A car with far fewer than typical may have been a second car or parked a lot; a car with far more may have been used for commuting or work. Neither is bad on its own. Ask why, and look at the records.

Where high mileage costs you

• Parts like the suspension, brakes, belts and the battery wear and need replacing.
• Larger repairs, such as a transmission or engine, become more likely as the car ages.
• Resale value is lower, and so is the price you will pay now.
• Warranties usually have mileage limits that high-mileage cars have passed.

Check that the mileage is honest

Look at the history report for odometer readings over time, and compare them with the car's wear. A drop or a gap deserves a question. See how to read a vehicle history report.

Let an expert decide

The most reliable answer is a professional inspection. A mechanic can tell you whether this particular car, at this mileage, is in good shape. See how to inspect a used car.
