How Much Mileage Is Too Much on a Used Car?
· 5 min read
There is no single number that makes a car a bad buy. A well-maintained car with 150,000 highway miles can be a better bet than a neglected one with 80,000. Miles matter, but so do age, maintenance and how the car was used.
Miles per year is a useful rough guide
Many drivers put around 12,000 miles a year on a car. Much higher can mean a long commute or heavy use. Much lower can mean it sat unused, which has its own problems, like dried seals and old fluids. Neither is automatically a problem, but both are worth asking about.
Highway miles and city miles are not the same
Steady freeway driving is easier on an engine, transmission and brakes than stop-and-go traffic. A car that commuted along Highway 50 or I-5 may be in better shape than one that made lots of short trips. Short trips, where the engine rarely warms up fully, are rough on engines.
Maintenance beats mileage
Ask for service records. Oil changes on schedule, a timing belt or chain handled when due, regular transmission fluid service and coolant changes tell you the owner cared. A stack of receipts with higher mileage is often a better buy than a clean car with a blank history.
Some things matter more at high mileage
- Timing belt replacement, if the engine uses one. If it is overdue and fails, repairs can be expensive.
- Transmission condition. Hesitation or harsh shifts are expensive problems.
- Suspension and bushings, which wear with miles.
- Oil leaks and consumption.
- Rust, less common here than in wetter states, but check underneath.
Reliability varies by model
Some engines and transmissions are known to run well past 200,000 miles. Others have known problems at 100,000. Look up your specific model and engine for common issues, and ask a mechanic who works on that brand.
Price should reflect miles
A higher-mileage car should cost less. If it does not, move on. If you are comparing two similar cars, the lower-mileage one is not automatically the better choice, but it should have a story to back that up.
Odometer honesty
Compare the odometer with the history report, the title and service records. If the numbers do not line up, that is a reason to walk away.
Bottom line
Judge the car, not just the number. A pre-purchase inspection will tell you more than the odometer.
