What Is a Good Mileage for a Used Car? A Practical Guide
When shopping for a used car, one of the first things you’ll hear about is mileage. But what exactly qualifies as “good mileage” for a used vehicle? And does high mileage automatically mean a car is unreliable? In this guide, we’ll break down everything you need to know about mileage, how it affects a car’s value and longevity, and how to evaluate whether a high-mileage car is still a good buy.
What Is Considered Good Mileage for a Used Car?
The general rule of thumb is that 12,000 kilometers per year is average for a well-driven car. This means a 10-year-old car with 120,000 kilometers on the odometer would be considered to have reasonable mileage. However, cars with higher or lower mileage can still be excellent choices depending on other factors like maintenance history, driving conditions, and overall condition.
How Much Mileage Is Too Much?
While 160,000 kilometers is often seen as the threshold where buyers should start being cautious, it’s not an automatic deal-breaker. Modern cars are built to last much longer than older models, with many capable of reaching 400,000 kilometers or more if properly maintained. Instead of focusing solely on the number, consider the car’s age, condition, and how it was driven.
High Mileage vs. Low Mileage: Pros and Cons
Pros of High-Mileage Cars
- Better Price: High-mileage cars are typically more affordable, making them a budget-friendly option.
- Regularly Driven: Cars that are used frequently tend to stay in better mechanical shape because their parts don’t sit idle and deteriorate.
- Proven Reliability: If a car has high mileage but is still running well, it’s a sign that it was likely well-maintained.
Cons of High-Mileage Cars
- More Wear and Tear: Higher mileage often means more strain on components like the engine, brakes, and suspension.
- Lower Resale Value: Once a car surpasses a certain mileage (e.g., 160,000 km), its resale value drops significantly.
- Potential for Costly Repairs: Major components like the transmission, timing belt, or water pump may need replacement sooner.
Pros of Low-Mileage Cars
- Less Wear and Tear: Fewer kilometers mean less stress on critical components.
- Higher Resale Value: Low-mileage cars tend to retain their value better, which is great if you plan to sell or trade it in later.
- Longer Lifespan: With fewer kilometers, the car has more life left in it.
Cons of Low-Mileage Cars
- Potential Neglect: Cars that aren’t driven regularly can suffer from issues like rust, brittle seals, or degraded fluids.
- Higher Price Tag: Low-mileage cars are often more expensive upfront.
How Driving Conditions Affect Mileage
- More Wear and Tear: Higher mileage often means more strain on components like the engine, brakes, and suspension.
- Lower Resale Value: Once a car surpasses a certain mileage (e.g., 160,000 km), its resale value drops significantly.
- Potential for Costly Repairs: Major components like the transmission, timing belt, or water pump may need replacement sooner.
Pros of Low-Mileage Cars
- Less Wear and Tear: Fewer kilometers mean less stress on critical components.
- Higher Resale Value: Low-mileage cars tend to retain their value better, which is great if you plan to sell or trade it in later.
- Longer Lifespan: With fewer kilometers, the car has more life left in it.
Cons of Low-Mileage Cars
- Potential Neglect: Cars that aren’t driven regularly can suffer from issues like rust, brittle seals, or degraded fluids.
- Higher Price Tag: Low-mileage cars are often more expensive upfront.
How Driving Conditions Affect Mileage

- Higher Price Tag: Low-mileage cars are often more expensive upfront.
How Driving Conditions Affect Mileage
Not all miles are created equal. The way a car is driven plays a huge role in determining its condition, regardless of the odometer reading.
Highway Driving
Cars driven primarily on highways tend to experience less wear and tear. Long-distance highway driving allows engines to operate at consistent speeds, reducing strain on components like the brakes and suspension. A car with 160,000 kilometers driven mostly on highways may be in better shape than a car with half the mileage driven in the city.
City Driving
Frequent stops, idling, and short trips take a toll on a car’s engine, brakes, and suspension. City driving also increases the risk of rust and corrosion due to exposure to moisture, road salt, and uneven pavement. If a car has high mileage from city driving, it’s worth inspecting these components closely.
How to Evaluate a High-Mileage Car
If you’re considering a high-mileage car, here are some steps to ensure it’s a smart purchase:
1. Check the Maintenance History
A well-maintained car can handle high mileage without major issues. Ask for service records to verify that regular maintenance was performed, including oil changes, timing belt replacements, and fluid flushes. Key intervals to check include:
- 5,000 km: Oil changes
- 100,000 km: Timing belt replacement
- As needed: Brake pad and rotor inspections
2. Inspect the Condition
Don’t rely solely on the odometer. Look for signs of wear and tear, such as:
- Rust or corrosion on the body or undercarriage
- Worn-out tires or brakes
- Leaks under the car (could indicate issues with the engine, transmission, or cooling system)
3. Test Drive the Vehicle
Take the car for a spin and pay attention to:
- How smoothly the engine runs
- Any unusual noises or vibrations
- The responsiveness of the brakes and steering
4. Get a Pre-Purchase Inspection
Hire a trusted mechanic to perform a thorough inspection. They can identify potential issues like:
- Timing belt wear
- Transmission problems
- Suspension damage
Common Issues with High-Mileage Cars
Even well-maintained cars can develop problems as they age. Here are some common issues to watch for:
1. Fuel Pump Damage
If the previous owner frequently drove with a low fuel tank, the fuel pump may be damaged. Ask about their driving habits and listen for unusual noises when starting the car.
2. Worn-Out Brake Pads
City driving and frequent stops can wear out brake pads quickly. Test the brakes during your test drive and ask the seller about recent replacements.
3. Timing Belt Breakage
A broken timing belt can cause catastrophic engine damage. If the car is nearing the 100,000-kilometer mark, consider replacing the timing belt as a precaution.
4. Automatic Transmission Failure
Stiff or awkward gear shifts could indicate transmission issues. Check the transmission fluid level and condition.
5. Water Pump Leak
Leaks in the water pump can lead to overheating. Inspect the engine bay for signs of coolant leaks.
6. Dead Battery
Batteries typically last 5–6 years. If the car is older, the battery may need replacement soon.
7. Damaged Tires
Worn-out tires are a safety hazard, especially in wet or snowy conditions. Inspect the tread depth and replace the tires if necessary.
How to Take Care of a High-Mileage Car
If you decide to buy a high-mileage car, proper care can extend its lifespan. Here are some tips:
1. Regular Maintenance
Stay on top of routine maintenance, including:
- Oil changes
- Fluid flushes (coolant, brake fluid, transmission fluid)
- Tire rotations and alignments
2. Address Issues Early
Don’t ignore small problems—they can turn into big expenses. Fix minor issues like squeaky brakes or leaking fluids before they worsen.
3. Clean the Car Regularly
Dirt, grime, and road salt can cause rust and corrosion. Wash your car frequently, especially during winter months.
4. Drive Responsibly
Avoid harsh acceleration, hard braking, and rough roads. Gentle driving reduces wear and tear on critical components.
Conclusion
So, what is a good mileage for a used car? While 120,000 kilometers over 10 years is a reasonable benchmark, the true measure of a car’s value lies in its condition, maintenance history, and how it was driven. High-mileage cars can still be reliable and affordable options if they’ve been well-cared-for, while low-mileage cars may come with hidden risks if neglected.
Before making a purchase, always inspect the car thoroughly, review its maintenance records, and consult a trusted mechanic. By focusing on both mileage and overall condition, you can find a used car that meets your needs and budget without compromising on reliability.
