When shopping for a used car, one of the first numbers most buyers look at is the mileage. A vehicle with 40,000 miles may immediately seem like a better choice than one with 120,000 miles, but mileage doesn’t tell the entire story.
Modern vehicles can last a long time when they’re properly maintained. In many cases, a well-cared-for vehicle with higher mileage can be a better purchase than a low-mileage vehicle that has been neglected.
So, how many miles is too many when buying a used car?
There isn’t one magic number. Instead, buyers should consider the vehicle’s age, maintenance history, driving conditions, make and model, overall condition, and price. Here’s what you should know before deciding whether the miles on the odometer are a reason to walk away.
What Is Considered High Mileage on a Used Car?
Traditionally, reaching 100,000 miles was considered a major milestone for a vehicle. Years ago, buyers often became nervous about purchasing anything that had crossed into six-digit mileage.
That’s much less meaningful today.
Many modern cars, trucks, and SUVs can reach 150,000, 200,000, or even more miles when properly maintained. Improvements in engines, transmissions, lubricants, manufacturing, and vehicle technology have helped extend the useful lives of many vehicles.
Generally, a used vehicle with more than 100,000 miles can be considered high mileage, but that doesn’t necessarily mean it’s worn out.
The better question is whether those miles make sense for the vehicle’s age and whether it has been maintained appropriately.
How Many Miles Should a Car Have Per Year?
A useful way to evaluate mileage is to compare it to the age of the vehicle.
Americans commonly drive somewhere around 12,000 to 15,000 miles per year, although individual driving habits vary significantly.
For example, a five-year-old car with 60,000 miles would have averaged about 12,000 miles annually. That’s perfectly reasonable.
A five-year-old car with 125,000 miles has clearly been driven much more extensively. That doesn’t automatically make it a bad vehicle, but you’ll want to learn more about how it was used and maintained.
Likewise, extremely low mileage isn’t always an automatic advantage.
A 10-year-old car with only 20,000 miles may sound fantastic, but vehicles can develop problems from sitting for extended periods. Rubber seals, hoses, tires, batteries, fluids, and other components can deteriorate with age regardless of how many miles are on the odometer.
Is 100,000 Miles Too Much for a Used Car?
Not necessarily.
A vehicle reaching 100,000 miles can still have years of useful life remaining. The condition and maintenance history become increasingly important as mileage climbs.
If the previous owner consistently changed the oil, maintained the cooling system, replaced worn components, serviced the transmission when appropriate, and addressed problems as they appeared, a 100,000-mile vehicle may still be in excellent condition.
Compare that with a 60,000-mile car that went thousands of miles beyond its oil-change intervals, overheated multiple times, or was driven aggressively without proper maintenance.
Mileage alone wouldn’t tell you which one is the safer purchase.
This is why buyers should evaluate the entire vehicle rather than using 100,000 miles as an automatic cutoff.
Is 150,000 Miles Too High?
Once you get into the 150,000-mile range, you should be more cautious, but these vehicles shouldn’t automatically be eliminated from your search.
At this mileage, the price should reflect the additional wear and the possibility of future repairs.
You’ll also want to pay particular attention to major components and maintenance items. Depending on the vehicle, things such as suspension components, wheel bearings, engine mounts, cooling-system parts, belts, hoses, alternators, starters, air-conditioning components, and transmission-related parts may have already been replaced or could eventually need attention.
A high-mileage vehicle with records showing that many of these components have already been serviced may actually be more attractive than one with no maintenance history.
Highway Miles vs. City Miles
Not all miles put the same amount of stress on a vehicle.
Imagine two cars that each have 100,000 miles.
One was driven primarily on the interstate during a long daily commute. The other spent its life making short trips around town.
Despite identical odometer readings, their wear could be significantly different.
Highway driving typically involves long periods at relatively consistent speeds. City driving involves considerably more starting, stopping, braking, accelerating, turning, idling, and shifting.
Short trips can also be harder on some components because the engine may repeatedly operate before reaching its ideal temperature.
That’s why a higher-mileage highway commuter can sometimes be in surprisingly good condition.
Maintenance History Matters More as Mileage Increases
The higher the mileage, the more important maintenance history becomes.
Ask whether service records are available and look for evidence that routine maintenance was performed consistently.
Oil changes are important, but they’re only part of the picture. Depending on the vehicle, maintenance can include transmission service, coolant replacement, brake service, spark plugs, filters, belts, timing belts or chains, differential fluids, and other manufacturer-recommended items.
You should also determine whether the vehicle has had any major repairs.
A vehicle with 130,000 miles and an excellent maintenance history may be a much smarter purchase than a vehicle with 80,000 miles and almost no documented service.
Research the Specific Make and Model
Mileage shouldn’t be evaluated in isolation because vehicles don’t all age the same way.
Certain engines and transmissions have excellent reputations for longevity, while specific model years or powertrains may have known problems that become more common as mileage increases.
Before purchasing a used vehicle, research the exact year, make, model, engine, and transmission whenever possible.
A particular model might generally have a great reputation while one specific model year has a known issue. Understanding those differences can help you determine whether a high-mileage example is worth considering.
Look Beyond the Odometer
Mileage is easy to compare, which is why buyers naturally focus on it. But there are many other clues about how a vehicle has been treated.
Look at the condition of the interior. Excessive wear on the driver’s seat, steering wheel, pedals, and controls can tell you something about the vehicle’s history.
Pay attention to how the car starts and idles. Listen for unusual knocking, ticking, grinding, squealing, or rattling noises.
During a test drive, notice how smoothly the transmission shifts, how the brakes feel, whether the steering wheel vibrates, and whether the vehicle pulls to one side.
Check the tires for uneven wear and look underneath the vehicle for signs of fluid leaks or significant corrosion.
A vehicle’s physical condition can tell you much more than the odometer alone.
Check the Vehicle History
A vehicle history report can provide additional information before you buy.
Depending on the information available, it may show reported accidents, title history, ownership changes, mileage records, service history, and other useful details.
Pay particular attention to mileage inconsistencies. If an older record shows higher mileage than a newer one, that’s something that needs to be investigated.
You should also consider how many owners the vehicle has had and whether there are indications of serious previous damage.
A history report isn’t a substitute for physically inspecting the car, but it can provide another important piece of the puzzle.
When Does High Mileage Become Too Risky?
There isn’t a universal mileage where a vehicle suddenly becomes a bad purchase.
Instead, mileage becomes “too high” when the vehicle’s condition, maintenance history, expected repairs, and asking price no longer make sense together.
A 170,000-mile vehicle might be an excellent inexpensive commuter if it has been maintained well and is priced appropriately.
On the other hand, paying a premium price for a high-mileage vehicle with questionable maintenance and obvious mechanical problems probably isn’t a great idea.
Your own plans matter, too.
If you only need an inexpensive second vehicle and drive a few thousand miles per year, a well-maintained high-mileage car may be ideal. If you commute 25,000 miles annually and hope to keep the vehicle for another decade, starting with significantly lower mileage may make more sense.
Don’t Forget About the Purchase Price
One major advantage of higher-mileage vehicles is affordability.
Mileage is one of the factors that affects resale value, which means a vehicle with 100,000 miles may cost substantially less than a comparable model with 40,000 miles.
That can create some excellent opportunities for used-car shoppers.
Instead of focusing exclusively on buying the vehicle with the fewest miles, consider the overall value you’re receiving for your money.
A newer, well-equipped vehicle with 90,000 miles may sometimes be a better purchase than an older vehicle with 50,000 miles, depending on their condition, history, and price.
Have a Used Vehicle Inspected
If you’re unsure about a used vehicle—particularly one with higher mileage—having it inspected by a qualified mechanic can provide valuable peace of mind.
A professional inspection may uncover issues that aren’t obvious during a quick walk-around or test drive.
The mechanic can examine important systems and help identify current problems or components that may require attention soon.
Spending a little time evaluating a vehicle before buying can potentially save you from expensive surprises later.
