There’s no magic number where a used car suddenly goes bad. A car with 180,000 km and a full service history can be a smarter buy than one with 90,000 km that was never maintained. What matters is how the kilometres were put on and how the car was looked after — not the odometer by itself.
The benchmark: about 20,000 km a year
The average vehicle in Canada covers roughly 15,000 to 20,000 km a year. That gives you a quick read on whether a car is high- or low-mileage for its age. A six-year-old car around 110,000 km is typical. The same car at 180,000 km is high; at 55,000 km it’s unusually low — which can be great, or can mean lots of short cold-weather trips that are hard on an engine.
Why low kilometres aren’t automatically better
Very low mileage on an older car deserves a question or two. Cars that mostly did short hops never fully warm up, which is harder on the oil and exhaust than steady highway driving. Rubber and seals also age with time, not just use. A garage-kept highway commuter at 140,000 km may have an easier life behind it than a city car at 70,000 km.
What actually predicts a long life
- Service records. Regular oil changes and scheduled maintenance matter more than the number on the dash.
- One or two owners rather than a long list of them.
- Rust. In salt-belt provinces this is often what ends a car, not the engine. Check the rockers, wheel wells, and underbody.
- Known model reliability. Some engines and transmissions simply last longer; a quick search on the specific model and year is worth it.
Mileage by vehicle type
Not all kilometres are equal. A diesel truck or a Toyota and Honda four-cylinder routinely passes 250,000–300,000 km with care. Performance engines, turbos driven hard, and some European models can need pricier work sooner. Match the mileage expectation to the specific car, not cars in general.
So when is mileage too high?
Treat very high kilometres — say, north of 200,000 km — as a signal to inspect more carefully and to expect wear items (suspension, clutch, brakes) to need attention sooner. It’s not a dealbreaker if the price reflects it and the car checks out. A mechanic’s inspection is cheap insurance at that point. Our inspection checklist walks through what to look for.
Frequently asked questions
How many kilometres is too many on a used car?
There’s no hard cut-off. Judge mileage against the car’s age (about 20,000 km a year is average) and, more importantly, its service history and model reliability. A maintained car at 180,000 km can outlast a neglected one at 90,000 km.
Is 200,000 km too much for a used car?
Not necessarily. Many reliable models run well past 200,000 km with care. At that mileage, budget for wear items and get an inspection, and make sure the price reflects the kilometres.
Do low kilometres justify a higher price?
Often, but not always. Pair low mileage with good records and no rust. See how to set a fair price for how to weigh it.
