What Is Good Mileage for a Used Car? (And What Matters More)
Good mileage for a used car is roughly 12,000 miles or less per year of age. A 5-year-old car with about 60,000 miles is average; noticeably less is low mileage, and more than about 15,000 miles a year is high. But mileage is only one clue. A well-maintained car with 120,000 highway miles can be a better buy than a neglected one with 60,000, so always weigh the miles against the car’s age, service history, condition and reliability record.
Use this guide to judge whether a used car’s mileage is good, what matters more than the odometer, how long modern cars last, and how to spot mileage red flags.
Key Takeaways
- Rule of thumb: about 12,000 miles a year is average; US drivers log roughly 13,000–14,000 on average.
- Good mileage: at or below average for the car’s age, with complete service records.
- Maintenance beats mileage: records, condition and how the miles were driven matter more than the number.
- Modern cars last: many reach 200,000 miles or more with good care.
- Verify the odometer with a vehicle history report and service records.
Average Mileage by Car Age
| Car age | Average mileage (about 12,000 a year) | Considered high above about |
|---|---|---|
| 1 year | 12,000 | 15,000 |
| 3 years | 36,000 | 45,000 |
| 5 years | 60,000 | 75,000 |
| 7 years | 84,000 | 105,000 |
| 10 years | 120,000 | 150,000 |
| 15 years | 180,000 | 225,000 |
Federal Highway Administration data puts the average American driver at roughly 13,000 to 14,000 miles a year, so the 12,000-mile rule of thumb is slightly conservative. Mileage well below average is not automatically a bonus, as explained below.
What Matters More Than Mileage
- Maintenance history: regular oil changes and scheduled services on time are the best predictor of a healthy car. Ask for receipts or a dealer service printout.
- How the miles were driven: steady highway miles cause far less wear on brakes, transmission and suspension than short stop-and-go city trips.
- Where the car lived: road salt causes rust; desert heat ages rubber, plastics and batteries.
- The model’s reliability record: some models routinely pass 200,000 miles, while others have known expensive failures at certain mileages.
- Number of owners: one or two long-term owners usually means more consistent care.
- Accident and title history: a clean title and no major accidents matter as much as the miles.
- Current condition: a pre-purchase inspection shows what the odometer cannot.
Is a High-Mileage Car a Bad Buy?
Not necessarily. High-mileage cars cost less, and a proven, well-maintained example can give many more years of service. The key is knowing which expensive maintenance items are due, or already done, at that mileage:
| Mileage | Common big-ticket items to check |
|---|---|
| 60,000–100,000 | Timing belt (on engines that use one), spark plugs, transmission fluid service, brakes, tires |
| 100,000–150,000 | Water pump, suspension parts, motor mounts, belts and hoses, battery |
| 150,000+ | Wear on transmission, AC compressor, starter and alternator, oil leaks, rust |
If a car is at or past a major service interval, ask for proof it was done. If not, subtract the cost from your offer. On many engines, a timing belt job alone can cost several hundred to over a thousand dollars.
Is a Low-Mileage Older Car Always Better?
A very low-mileage older car can be a great find, but it has its own risks. Cars that sit for long periods can develop dried-out seals and gaskets, old fluids, flat-spotted or aged tires, weak batteries and fuel system problems. Tires and rubber parts age even when a car is not driven. Check the tire date codes and look for service records showing regular use or proper storage.
How Many Miles Can a Car Last?
Modern cars are built to last much longer than cars from past decades. With regular maintenance, many cars reach 200,000 miles or more, and some well-known models regularly go beyond 250,000. According to S&P Global Mobility, the average age of vehicles on US roads was about 12.8 years in 2025, and many of those vehicles have well over 150,000 miles.
How long a particular car lasts depends on its design, maintenance and how it is driven. Rust, a major transmission failure or an expensive repair that costs more than the car is worth are usually what end a car’s life, not a specific odometer number.
Mileage and Electric Vehicles
For a used EV, battery health matters more than mileage. EVs have fewer moving parts, no oil changes and less brake wear thanks to regenerative braking, but their batteries lose some capacity over time. Ask for a battery health report or check the car’s estimated range when fully charged, and confirm how much of the manufacturer’s battery warranty, often 8 years or 100,000 miles, remains.
How to Check Whether the Mileage Is Real
- Get a vehicle history report (such as Carfax or AutoCheck) and look for consistent odometer readings over time.
- Check the government database: the National Motor Vehicle Title Information System (NMVTIS) shows title brands and some odometer records.
- Compare service records, inspection stickers and oil change stickers with the current reading.
- Match wear to miles: a heavily worn steering wheel, pedals and driver’s seat on a “low-mileage” car is a warning sign.
- Watch for title brands such as “not actual mileage” or “exceeds mechanical limits.”
Odometer fraud is illegal under federal law, but digital odometers can still be tampered with, so cross-check several sources.
How Mileage Affects Price and Insurance
Lower mileage usually raises a car’s value, and higher mileage lowers it, often significantly once a car passes 100,000 miles. That makes high-mileage cars a good value if they have been cared for. Mileage has little effect on insurance for the car itself, although your own yearly driving can affect your premium.
Quick Checklist: Judging a Used Car’s Mileage
- Divide the miles by the car’s age to see if they are below, at or above average.
- Ask how the car was mainly driven: highway or city.
- Request service records and check that major services are up to date.
- Get a vehicle history report and look for consistent odometer readings.
- Look up the model’s reliability and known problems at that mileage.
- Pay for a pre-purchase inspection before you buy.

Used Car Mileage FAQ
Around 12,000 miles or less per year of age is considered good. For example, about 60,000 miles on a 5-year-old car is average, and less is low mileage.
There is no hard cutoff. More than about 15,000 miles per year of age is high, and many buyers get cautious above 100,000 to 150,000 miles, but a well-maintained car with good records can still be a good buy.
Not for most modern cars. Many run well past 200,000 miles with proper maintenance. At 100,000 miles, check that major services such as the timing belt and transmission fluid have been done.
It depends on condition and history. A newer high-mileage car often has more modern safety features and fewer age-related problems, while an older low-mileage car may have aged rubber parts and tires. Service records decide it.
Federal data puts the average at roughly 13,000 to 14,000 miles a year, while many buyers use 12,000 miles a year as a rule of thumb.
Many modern cars last 200,000 miles or more with regular maintenance. The average age of vehicles on US roads is about 12 to 13 years.
Yes. Highway driving causes less wear on brakes, transmission, suspension and engine than stop-and-go city driving with many cold starts.
Compare the reading with a vehicle history report, service records and inspection stickers, look for wear that does not match the miles, and check the title for mileage brands.
