Acheter une voiture d'occasion — préparez-vous, vérifiez, négociez.
1. Private seller or dealer?
- Private seller: lower price, but no warranty and more risk
- Dealer: higher price, legal protections, limited warranty
A private seller is cheaper but with no warranty: the rule is « as is », and QST is still owed at the SAAQ on transfer. A dealer costs more but offers the legal warranty of fitness under the Quebec Consumer Protection Act, plus financing. For a first purchase without experience, the dealer remains safer.
| Criterion | Private seller | Dealer |
|---|---|---|
| Price | Lower | Higher |
| Legal warranty of fitness | ❌ (« as is ») | ✅ |
| GST (5 %) | ❌ | ✅ |
| QST (9.975 %) | ✅ | ✅ |
| Financing offered | ❌ | ✅ |
| Risk | Higher | Lower |
2. Check the vehicle history
Always request a vehicle history report before buying:
- CarFax Canada — about 50 $
- Reveals: accidents, previous owners, mileage, liens
3. Mechanical inspection
Get an independent mechanical inspection:
- Mechanic of your choice (not the seller's)
- Cost: 100 to 200 $
- Leverage to negotiate or walk away from the purchase
4. Negotiating the price
Price is almost always negotiable:
- Compare on AutoHebdo, Kijiji, Marketplace
- Typical margin: 5 to 15 % negotiable
- Use defects found as arguments
5. Transfer and registration
The transfer happens at the SAAQ:
- Seller + buyer together (or power of attorney)
- You pay: QST 9.975 % on the price + registration fees
- Car insurance before taking the car (mandatory)

7. Frequently asked questions
The most common questions on used-car purchases: paying QST even between private sellers, inspection at an independent mechanic, buying without Canadian credit, used-car warranty, and required road test.
Do I pay QST if I buy from a private seller?
Yes — QST (9.975 %) is owed on every used-vehicle transfer in Quebec, including private sales.
It's calculated on the higher of:
- The sale price
- The vehicle's value per Hebdomag Auto (SAAQ reference)
You pay it at the SAAQ during the ownership transfer. GST (5 %) only applies to sales by a dealer.
Tip: be honest about the price — SAAQ compares it to the reference value, and undervaluation is fraud.
Is the independent mechanical inspection really worth it?
Yes — non-negotiable. Costs 100 to 200 $ and reveals problems the seller won't disclose: rust under the body, brake wear, transmission issues, hidden accident damage.
On average, the inspection report saves you 500 to 3,000 $ through negotiation or by avoiding a problem vehicle.
Never accept « the seller already had it inspected » — ALWAYS use your own mechanic (not the one recommended by the seller). CAA-Québec offers a verification service if you don't have a trusted mechanic.
Can I finance a used car without Canadian credit?
Yes, but the rates are punishing. Specialty « subprime » lenders accept newcomers with no Canadian credit at rates of 12 to 25 % (vs 5 to 8 % for good credit).
Better strategies:
- Save and buy outright a reliable 3,000 to 7,000 $ vehicle as your first car
- Wait 12 to 18 months while building Canadian credit with a secured credit card
- Ask a Canadian relative to co-sign
Avoid « no credit, no problem » dealers — their markups are huge.
Is there a warranty on a used car?
The Quebec Consumer Protection Act grants a « legal warranty of fitness » on dealer purchases — the vehicle must last « a reasonable time » given its price and mileage.
A 3-year-old car with 80,000 km should run 1 to 2 years without major repairs; if it breaks down within 30 to 60 days, the dealer must repair, refund or replace.
Private sales have no warranty — the rule is « as is ». Manufacturer warranty (powertrain, electrical) may still apply if not expired.
Is a road test required before buying?
Not legally required, but absolutely essential. Drive the vehicle for at least 30 minutes on highway AND city streets. Check for:
- Smooth gear shifts
- No shaking at high speed
- Brakes that don't pull to one side
- Air conditioning AND heating working (critical for Quebec winters!)
- No warning lights on the dashboard
- All windows and locks functional
- No unusual noises at low or high speed
Don't be intimidated — sellers who refuse a real road test usually have something to hide.
