Buying a used car in Quebec is a good decision when you work through a used car buying checklist and take the time to check things properly. But between the excitement of finding the right model and the pressure to close quickly, many buyers skip steps that cost them dearly afterwards. This checklist was designed for local conditions: harsh winters, road salt, SAAQ procedures and the real differences between buying from a dealership and from a private seller. Print it, keep it in your pocket and tick off every point before you sign.
1. Documents and history
Before you even touch the vehicle, ask to see the paperwork. A transparent seller has it on hand already. Here is what you should require:
- The registration certificate (proof that the seller is the owner or an authorized dealer).
- The full vehicle identification number (VIN) visible on the dashboard, the driver's door and the documents: all three must match.
- Maintenance invoices: oil changes, brakes, tires, major repairs. A well-kept logbook is worth gold.
- The vehicle history report (Carfax or CarProof) to check reported accidents, consistent mileage and origin.
With a dealer holding an OPC licence, like BonAuto (licence no. 2110539-1), you are also entitled to a detailed sales contract that must state the condition of the vehicle. It is a protection you will never get from a private seller. Learn how to break down the history report with our guide to reading a Carfax or CarProof report.
2. The mechanical inspection
A visual inspection on your part does not replace a real inspection by a mechanic, but it lets you quickly rule out bad surprises. In Quebec, salt and freeze-thaw cycles attack vehicles from underneath: rust is enemy number one.
- Underneath the vehicle: look for perforating rust on the frame, rocker panels, wheel wells and brake lines.
- Body: panel gaps, paint colour differences, traces of filler (signs of a repaired accident).
- Tires: even wear on all four? Uneven wear reveals an alignment or suspension problem.
- Under the hood: oil and coolant levels, belts, leaks, corrosion on the battery.
- Fluids: burnt or milky oil, transmission fluid that smells burnt.
The most worthwhile step remains taking the vehicle to an independent garage for a pre-purchase inspection of $100 to $200. It is cheap insurance. See the details in our complete guide to the pre-purchase mechanical inspection.
3. The test drive: what to test
A 5-minute test drive in the parking lot is not enough. Plan on at least 20 to 30 minutes, on varied roads: city, highway and, if possible, a hill. Start from cold to hear the engine sounds on wake-up.
- Cold start: does the engine run smoothly? Is there persistent blue or white smoke from the exhaust?
- Steering: wheel centred, no pulling to one side, no vibration at high speed.
- Brakes: straight braking, no pulsing or squealing, firm pedal.
- Transmission: smooth gear changes (automatic) or a clutch that bites cleanly (manual), no jerking.
- Suspension: go over a bump: no dull thud or excessive bounce.
- Electronics: air conditioning, heating, rear defroster (essential in winter), windows, backup camera, all dashboard warning lights.
Also check that winter tires are included or available. In Quebec, they are mandatory from December 1 to March 15 and must carry the mountain/snowflake symbol. A second set mounted on rims can mean savings of several hundred dollars.
4. Carfax, SAAQ and administrative checks
Beyond the accident history, certain administrative checks save you from big headaches. The most important: making sure the vehicle has no debt or seizure registered against it. Run a search with the RDPRM (Quebec's register of personal and movable real rights): if a financial institution has a right on the vehicle, you could inherit the debt.
- Cross-check the mileage on the Carfax report with the one displayed and the maintenance invoices.
- Confirm that the VIN matches between the vehicle, the report and the registration.
- Run an RDPRM search (a consultation fee applies) to detect a registered debt.
- Confirm that the vehicle is not declared a total loss or “rebuilt” without disclosure.
Buying from a dealer greatly simplifies these steps: they must deliver a vehicle free of debt and they handle the paperwork. This is also where the legal warranty under the Consumer Protection Act comes in, which does not exist in a sale between private individuals.
5. Negotiation, taxes and transfer
Once the vehicle is approved, it is time for the home stretch. First understand the real costs by type of sale, because taxes are not calculated the same way:
| Item | At a dealership | Between private individuals |
|---|---|---|
| Taxes | GST 5% + QST 9.975% = 14.975% of the price | No GST; QST of 9.975% collected by the SAAQ |
| Tax calculation base | Sale price, minus the trade-in value | The higher of the price paid and the value in the vehicle valuation guide (Guide d'évaluation) |
| Trade-in value deducted | Yes, reduces the taxable amount | Not applicable |
| Legal warranty (LPC) | Yes, depending on age and mileage | No |
The trade-in value deduction at a dealership is a concrete advantage: if you trade in your old vehicle, you only pay taxes on the difference. Also note that a vehicle gift between eligible relatives (spouse, parent, child, grandparent, brother or sister, etc.) is exempt from QST at the SAAQ, provided you fill out the form VD-80.1 and prove the relationship at the counter.
For the transfer, plan on the 2026 SAAQ fees: $10.60 registration fee, $2.70 for issuing a new standard plate and $217.41 in annual duties for a passenger vehicle. Add the new tire levy and an RDPRM search, whose amounts should be checked at the source before your appointment. On the negotiation side, rely on facts: a defect found at the inspection, upcoming maintenance, or tires at the end of their life are solid arguments for adjusting the price.
