Most used-car mistakes are avoidable with an hour of careful checking. You don’t need to be a mechanic — you need a routine. Here’s the one to run before you hand over any money, from the history report to the test drive.
Before you go: the paperwork
- Get the VIN from the seller and run a vehicle history report. It flags accidents, previous owners, odometer issues, and liens.
- Confirm the seller’s name matches the ownership/registration.
- Ask for service records. Gaps aren’t automatically bad, but a documented history is worth paying a little more for.
The walk-around (daylight only)
See the car in person, in daylight, ideally dry weather. Then check:
- Body and panels: uneven gaps or mismatched paint can hint at past collision repair.
- Rust: look at the rocker panels, wheel wells, and underbody — the parts a quick wash hides. This matters more in salt-belt provinces.
- Tires: even wear across all four, and matching brands. Uneven wear can mean alignment or suspension problems.
- Fluids: oil should not be gritty; no milky residue under the cap; no puddles where it was parked.
- Lights and glass: everything works, no cracks creeping across the windshield.
Inside the car
Start it cold if you can — a seller who’s already warmed it up may be hiding a hard cold start. Watch that the dashboard warning lights illuminate and then clear. Check that the air conditioning blows cold, the heat blows hot, and the infotainment, windows, and locks all work. Make sure wear on the seat, pedals, and steering wheel roughly matches the odometer.
The test drive
Drive it the way you actually will — some city, some highway. Pay attention to:
- Cold-start behaviour and any smoke from the exhaust
- Smooth, predictable shifts; no slipping or clunks
- Straight tracking with hands light on the wheel; no pull
- Brakes that stop evenly without shudder, grinding, or a soft pedal
- Unusual noises over bumps, which can point to worn suspension
When in doubt, get an inspection
For a few hundred dollars, a mechanic’s pre-purchase inspection can save you thousands — especially on a higher-kilometre car or a private sale with no records. It’s the cheapest insurance in the whole process, and a trustworthy seller won’t object.
Frequently asked questions
What should I check before buying a used car?
Run a history report from the VIN, confirm ownership, inspect the body and underbody for rust and repairs, check tires and fluids, test all electronics, and take a proper test drive on city and highway roads.
Is a pre-purchase inspection worth it?
Yes, especially on private sales and higher-mileage cars. A few hundred dollars upfront can reveal problems that cost thousands later.
What are the biggest red flags?
A refused VIN, pressure for a deposit before viewing, mismatched paperwork, fresh undercoating hiding rust, and a price far below market with no explanation. More on those in spotting a good deal.
