Does car mileage matter?

Summary

Mileage matters, but it isn’t everything. Know the numbers for low, average and high mileage.
Maintenance and vehicle history are crucial to the overall condition of a vehicle.
Review the history of a vehicle with our checklist.
If properly maintained, high-mileage vehicles can be dependable and are typically lower priced.

Age is just a number

When shopping for a used vehicle, the odometer is often the first thing a buyer checks. While mileage is a good way to help gauge the quality and potential lifespan of a vehicle, it isn’t the only thing that matters. Factors like driving patterns, maintenance and weather can also affect the overall vehicle condition. To know if you’ve really found the used vehicle of your dreams, you need to look beyond the odometer.

An average vehicle accrues around 12,000–15,000 miles every year. To see if a used vehicle is in a good mileage range, divide the number of miles by the vehicle’s age. For example, a 4-year-old vehicle with 48,000 miles would be considered a good mileage range. If a vehicle the same age had 29,000 miles, that would be considered low mileage. The lower the mileage the more likely it is to have less wear and tear.

To be considered high mileage, a vehicle has typically 70,000–100,000 miles. While 100,000 used to mean the end of a car’s lifespan, some vehicles can last up to 200,000 miles if properly maintained. Once a vehicle gets close to 100,000 miles, it may require frequent repairs or other expenses to maintain it.

Mileage Category	Mileage Range	Typical Vehicle Age
Low Mileage	Under 30,000 miles	Usually under 2–3 years old
Average/Mid Mileage	30,000–70,000 miles (12,000–15,000 miles a year)	Around 3–6 years old
High Mileage	Over 70,000 miles	Typically, over 6 years old
These mileage categories and typical vehicle ages are general guidelines only based on typical annual driving patterns. Actual mileage, age, condition, and value will vary by vehicle, and this chart does not constitute a guarantee or warranty.

Beyond the odometer

Once you’ve assessed the mileage of a used vehicle you’re interested in, it’s time to get personal. The difference between a well-maintained vehicle and a poorly maintained one can be drastic, and that can really affect the wear and tear in the long run. Check the CARFAX® Vehicle History Report to learn more about the vehicle’s history.

Did the vehicle have routine maintenance like oil changes, fluid services and more? A vehicle with low mileage but has never had an oil change could come with its own set of problems and cost more in repairs. In that case, a higher mileage with routine service visits may be more dependable on the road. Proper maintenance can help lead to fewer issues down the road.

Was it driven mostly on the highway or during city rush hour? Daily stop-and-go driving can increase wear on brakes, suspension and transmission compared to cruising on a highway.

Has the vehicle been in any collisions? Has it had multiple owners? If the answer is yes to either question, you may be risking more unknowns about the vehicle and how well it will hold up over the years.

The mileage evaluation checklist

Review the checklist below for some advice on buying a used vehicle. We’ve got some tips to help you find your mileage match.

Compare mileage vs. age

Calculate average miles per year to see if the car is in the low, average or high mileage range.

Check odometer consistency in the vehicle history report

Look for rollbacks, major mileage jumps or repairs that signal heavy use at certain mile markers.

Review maintenance records for mileage-based services

Routine maintenance—such as oil changes, transmission fluid checks, brake replacements and coolant flushes—should be performed at specific mileage intervals. Follow the vehicle manufacturer’s maintenance schedule for mileage‑based services.

Confirm mileage, age and condition

Interior wear, engine bay condition and brake/tire wear should match expectations for the mileage of the vehicle.

Understand the type of miles driven

Highway miles are generally easier on the vehicle, while city/short-trip miles can increase wear.

Look for a warranty or certification

Certification and warranties are especially reassuring when considering a mid- to high-mileage vehicle, since they help reduce risk of costly repairs.

Research expected longevity for this model

Depending on the model and how it is maintained, some vehicles can exceed 200k miles. Which means 120,000 miles may be midlife for certain vehicles.

Consider your future mileage needs

How many miles do you typically drive a year? Will mileage matter to you at resale?

More miles, no problem

Sometimes buying a high-mileage used vehicle is the smart choice. Typically, higher mileage vehicles between 100,000–150,000 miles tend to be more affordable with a lower price point. If you find a certified used vehicle in the higher mileage range with a clean history and routine maintenance, it may be a great deal. Just look for terms like certified, inspected, extended warranty and routine maintenance—signs you’ve found a high-mileage vehicle worth considering.

IMPORTANT RECALL INFORMATION: Before a CarBravo vehicle is listed or sold, GM requires dealers to complete all safety recalls. However, because even the best processes can break down, we encourage you to check the recall status of any vehicle through your GM account and NHTSA.
