Buying a high-mileage used car can feel risky. You see a vehicle with 150,000 km, 180,000 km, or even more on the odometer, and the first thought is often, “How much longer will this car last?”

The truth is that mileage is only one part of the story.

A well-maintained vehicle with 160,000 km can sometimes be a better purchase than a poorly maintained vehicle with 100,000 km. What matters is how the vehicle was driven, how it was maintained, what repairs have already been completed, and what condition it is in today.

If you are buying a high-mileage used car in Canada, especially for daily driving, there are several things you should check before making a decision.

What Is Considered High Mileage for a Used Car in Canada?

There is no single kilometre number that automatically makes a used car “high mileage.”

Many Canadian buyers start paying closer attention once a vehicle reaches around 150,000 km. However, that does not mean a vehicle becomes a bad purchase at 150,001 km.

A vehicle with 150,000 km may still have plenty of useful life left if it has been properly maintained. On the other hand, a vehicle with fewer kilometres could have expensive problems if previous owners neglected regular maintenance.

Instead of asking only:

“How many kilometres does it have?”

Ask:

“How was it maintained?”

Look at the vehicle's service records, accident history, overall condition, and the type of driving it experienced.

Highway kilometres, for example, can be very different from years of short city trips and stop-and-go driving. The odometer gives you a number, but the vehicle's history helps explain that number.

Is It a Good Idea to Buy a Used Car With Over 150,000 Kilometres?

Yes, it can be.

A used car with more than 150,000 km may offer a lower purchase price than a similar newer vehicle with fewer kilometres. For buyers working with a specific budget, this can open up more options.

But the lower price should not be the only reason you choose it.

Before buying a vehicle over 150,000 km, consider:

  • Its maintenance history

  • Previous accidents or damage

  • Engine and transmission condition

  • Brake and suspension condition

  • Tire condition

  • Rust or corrosion

  • Service records

  • Vehicle history report

  • Results of a professional inspection

  • Any repairs that have already been completed

A high-mileage vehicle with a strong maintenance record can be worth considering. A high-mileage vehicle with an unclear history and several warning signs deserves much more caution.

What Are the Risks of Buying a High-Mileage Used Car From a Dealership?

Buying from a dealership does not automatically remove the risks associated with an older or high-mileage vehicle. At the same time, buying privately does not automatically make a vehicle safer.

The main risk with any high-mileage used vehicle is that some components have experienced more wear.

Depending on the vehicle, you may eventually need to deal with repairs involving:

  • Brakes

  • Suspension components

  • Wheel bearings

  • Tires

  • Battery

  • Belts and hoses

  • Cooling system components

  • Engine seals

  • Transmission components

  • Electrical parts

These are not guaranteed problems. They are simply areas that deserve attention as a vehicle gets older and accumulates kilometres.

That is why the inspection and service history are so important.

A dealership vehicle should still be evaluated based on its individual condition rather than its odometer alone.

Common Mechanical Issues With High-Mileage Used Vehicles

High mileage does not mean a vehicle will immediately develop mechanical problems. However, normal wear becomes increasingly important as a vehicle gets older.

1. Brake Wear

Brake pads and rotors are wear items. Their condition depends on driving habits, road conditions, vehicle weight, and previous maintenance.

During a test drive, pay attention to unusual noises, vibrations, or changes in braking feel.

2. Suspension Wear

High-mileage vehicles can develop worn suspension components.

You may notice:

  • Clunking noises

  • Excessive bouncing

  • Uneven tire wear

  • Steering that feels less controlled

  • The vehicle pulling or drifting

A proper inspection can help identify components that may need attention.

3. Wheel Bearings

A worn wheel bearing can sometimes produce a humming, rumbling, or grinding sound that changes with vehicle speed.

It is not always easy for a buyer to diagnose this during a short test drive, which is another reason an inspection is valuable.

4. Transmission Wear

Transmission problems can be among the more expensive repairs.

During a test drive, pay attention to how the transmission shifts. Delayed engagement, harsh shifting, slipping, or unusual noises should be investigated before purchasing.

5. Engine Leaks

As vehicles age, seals and gaskets can develop leaks.

Look underneath the vehicle and around the engine compartment for signs of fluid leaks. Also check whether the seller has maintenance records showing regular oil and fluid servicing.

Regular fluid and maintenance work can play an important role in long-term vehicle life.

6. Cooling System Problems

The cooling system deserves attention on an older vehicle.

Check for signs of coolant leaks, overheating, damaged hoses, or other cooling-system concerns. An overheating engine can lead to serious and expensive problems.

7. Rust and Corrosion

Rust is especially important for Canadian used-car buyers.

Canadian winters can expose vehicles to snow, moisture, road salt, and changing temperatures. Rust may appear around wheel arches, doors, rocker panels, the underside, and other areas.

Do not only look at the paint. If possible, have the underside of the vehicle inspected as well. Rust can sometimes be hidden underneath the vehicle or behind panels.

How to Check a High-Mileage Used Car Before Buying

If you are buying a high-mileage used car, do not make your decision from the listing photos and odometer reading alone.

Use this process.

1. Check the Vehicle History

Ask for a vehicle history report and review it carefully. A CARFAX Canada Vehicle History Report can provide information about accident history, damage, service records, recalls, odometer readings, and other vehicle-history details. 

Look for information about:

  • Previous accidents

  • Reported damage

  • Registration history

  • Number of previous owners

  • Service records when available

  • Potential inconsistencies in the vehicle's history

A history report is useful, but it should not replace a physical inspection.

2. Review the Maintenance Records

Maintenance records can tell you much more than the odometer.

Look for evidence of regular:

  • Oil changes

  • Brake servicing

  • Tire replacement

  • Fluid servicing

  • Major scheduled maintenance

  • Repairs

A vehicle with documented maintenance gives you more information about how it was cared for.

3. Inspect the Exterior

Walk around the vehicle during daylight if possible.

Look for:

  • Rust

  • Mismatched paint

  • Uneven panel gaps

  • Scratches and dents

  • Cracked lights

  • Windshield damage

  • Uneven tire wear

None of these automatically mean you should walk away, but they are worth understanding before you buy.

4. Check the Interior

The interior can provide clues about how the vehicle was used.

Check the:

  • Seats

  • Steering wheel

  • Pedals

  • Dashboard

  • Windows

  • Air conditioning

  • Heating

  • Infotainment system

  • Lights

  • Warning indicators

Heavy wear is not necessarily a mechanical problem, but it can help you understand the vehicle's overall condition.

5. Take a Proper Test Drive

Do not rush through the test drive.

Drive at different speeds and pay attention to:

  • Engine noise

  • Transmission shifts

  • Steering

  • Braking

  • Suspension noises

  • Road noise

  • Warning lights

  • Heating and air conditioning

If something feels unusual, ask about it before moving forward.

6. Get a Professional Inspection

This is one of the most important steps when buying a high-mileage used car. A qualified mechanic can inspect areas that are difficult for the average buyer to evaluate. A professional inspection may identify wear or repairs that are not obvious during a quick test drive.

A professional inspection is especially important when buying a high-mileage used car because it can help identify mechanical issues that may not be obvious during a quick test drive. 

High Mileage vs. Low Mileage: Which Used Car Is Better?

It is tempting to assume that the vehicle with the lowest odometer reading is automatically the better choice.

That is not always true.

Imagine you are comparing two similar vehicles.

Vehicle A

  • 110,000 km

  • Limited service records

  • Several overdue maintenance items

  • Original older tires

  • Signs of neglected repairs

Vehicle B

  • 165,000 km

  • Consistent service records

  • Recent maintenance

  • Good tires

  • Clean inspection

  • No major warning signs

The second vehicle may deserve serious consideration despite having more kilometres.

This is why maintenance history, not mileage, is such an important comparison when shopping for a used vehicle.

What About a Used Car With 150,000 Kilometres?

A used car with 150,000 km should not automatically be rejected.

Instead, use 150,000 km as a point where you become more thorough with your research.

Ask:

What maintenance has already been done?

What repairs might be coming up?

Does the vehicle have a clean history?

Does the current condition match the price?

Has the vehicle been inspected?

The answers to these questions are more useful than simply looking at the number on the odometer.

Can You Find a High-Mileage Used Car With Warranty Coverage?

It is possible for some used vehicles to have warranty or other coverage, but buyers should always confirm exactly what is included.

Do not assume that every high-mileage vehicle comes with the same coverage.

Before purchasing, ask:

  • What does the warranty cover?

  • How long does the coverage last?

  • Is there a kilometre limit?

  • What parts are excluded?

  • Are labour costs included?

  • Are there deductibles?

  • What maintenance requirements apply?

If a vehicle is advertised with warranty coverage, get the details in writing and understand the terms before signing.

Are High-Mileage Used Cars Cheaper to Own?

Not necessarily.

A lower purchase price can be attractive, but ownership costs depend on the vehicle itself.

A high-mileage vehicle may have a lower upfront cost but could require more maintenance. A newer vehicle may cost more to purchase but potentially require fewer immediate repairs.

Think about your total cost of ownership, including:

  • Purchase price

  • Financing

  • Insurance

  • Fuel

  • Tires

  • Routine maintenance

  • Repairs

  • Registration

  • Expected ownership period

The cheapest vehicle to buy is not always the cheapest vehicle to own.

When Should You Walk Away From a High-Mileage Used Car?

Mileage by itself is usually not enough reason to walk away.

But several warning signs together should make you stop and investigate further.

Be cautious if you find:

  • Major unexplained mechanical noises

  • Serious rust or corrosion

  • Overheating

  • Transmission slipping

  • Multiple dashboard warning lights

  • Missing or inconsistent vehicle history

  • Poor maintenance records

  • Significant fluid leaks

  • Uneven or suspicious tire wear

  • Evidence of major undisclosed damage

  • A seller who refuses a reasonable inspection

If the vehicle does not feel right or the seller is unwilling to provide reasonable information, there are always other used cars to consider.

Is Buying a High-Mileage Used Car From a Dealership Worth It?

For the right vehicle, it can be.

The important thing is not simply whether the car has high kilometres. You want to understand what you are buying.

A dealership can be a useful place to compare vehicles, ask questions about the vehicle's history and condition, and discuss available financing or coverage where applicable.

But you should still do your own research.

Review the vehicle history, inspect the vehicle, take it for a test drive, and ask questions about its maintenance.

At OVI Motors, shoppers looking for a used vehicle can use this same approach when evaluating higher-mileage options. Rather than focusing only on the number on the odometer, compare the vehicle's overall condition, history, maintenance, and value.

Final Thoughts: Should You Buy a High-Mileage Used Car?

Buying a high-mileage used car can be a smart decision when the vehicle has been properly maintained, and its condition supports the price.

Do not let a number like 150,000 km automatically decide for you.

Look at the complete picture: maintenance history, vehicle condition, previous use, accident history, inspection results, expected repairs, and overall value.

For Canadian buyers, also pay close attention to rust, winter wear, tires, brakes, and the condition of components that have been exposed to years of Canadian driving conditions.

The right high-mileage used car is not necessarily the one with the fewest kilometres. It is the one that has been properly maintained, carefully inspected, fairly priced, and suited to the way you plan to drive it.
