checklist complète avant d’acheter une voiture usagée

Buy a used car can be a great way to save, but it's also a risky transaction.

Hidden defects, unpaid debts, tampered with mileage... without good preparation, a purchase that seemed advantageous can quickly turn into a nightmare.

That is why it is essential to follow a clear and complete checklist prior to completing the transaction.

By checking the documents, history and condition of the vehicle, you considerably reduce unpleasant surprises and ensure a safe purchase.

Here is the checklist and our advice to follow before buying a used car privately in Quebec.

1. Check vehicle documents

First of all, make sure that the seller can provide the essential legal documents :

  • Registration certificate : it must be in the name of the seller. If not, be wary.
  • Written and signed sales contract : always require written proof to avoid disputes.
  • Research at the RDPRM : the Register of personal and real moveable rights allows you to check whether the vehicle is still linked to a debt or a pledge with a financial institution.
  • History report (CARFAX or equivalent) : it completes the legal check by revealing accidents, recalls and major repairs.

💡Tip : keep a copy of all of these documents. They will be able to protect you in the event of a future dispute.

2. Review vehicle history

History often reveals what the seller is not saying:

  • Serial number (NIV/VIN) : always check that the VIN on the vehicle matches the VIN on the documents.
  • Accident history : some may have damaged the structure of the vehicle.
  • Mileage : watch out for fraud, such as counting down the clock. Compare the information from the CARFAX and the odometer.
  • Safety reminders : Make sure that all recalls have been resolved by the manufacturer.

💡 Tip : a damaged vehicle is not necessarily a bad buy, but always require proof of repair.

3. Mechanical and visual inspection

Even if the used car seems nice, an inspection is a must.

External inspection

  • Check the body: bumps, rust, repair marks.
  • Check the condition of the tires and rims.

Internal inspection

  • Check the dashboard (indicator lights).
  • Check belts, seats, windows, and air conditioning.

Mechanical check

  • Motor : abnormal noises, oil leaks.
  • Brakes and suspension : wear and tear, efficiency.
  • Direction : reactivity and stability.

Test drive

  • Test the vehicle on various types of roads.
  • Check acceleration, braking, and transmission.

💡 Tip : if you have doubts, call in an independent mechanic. The cost is low compared to the costs of an undetected repair.

4. Legal and financial audits

A safe purchase also involves financial and legal aspects:

  • Real owner : make sure that the seller is the one registered with the SAAQ.
  • Bonds and debts : confirm via the RDPRM that no creditor has rights to the vehicle.
  • Taxes to be expected : in Quebec, you must pay the GST and TVQ during the transfer to the SAAQ (except in special cases).
  • Insurance : contact your insurance company to estimate the cost before buying.

5. Questions to ask the seller

Some simple questions can avoid a lot of problems:

  • Why are you selling the vehicle?
  • Has the vehicle been maintained regularly?
  • Do you have maintenance and repair bills?
  • Are there any known problems (mechanical or electronic)?

💡 Tip : a transparent seller will respond without hesitation and provide the necessary evidence.

6. Negotiation and conclusion of the transaction

Once the checklist is complete, use the information collected to negotiate.

  • Rely on the results : scheduled maintenance or worn tires may justify a price reduction.
  • Set a fair price : compare with other similar ads in Quebec.
  • Finalize the transaction safely : prefer a traceable payment (certified check, bank transfer). Request a written receipt.

7. Post-purchase steps

Your new car is not yet entirely yours until these steps are completed:

  • Transfer of ownership to the SAAQ : required to register the vehicle in your name.
  • Auto Insurance Update : you must insure the vehicle before driving it.
  • Preventive maintenance : an oil change and a general check are always recommended after a purchase.

8. FAQ — Buying a used car in Quebec

What documents do you absolutely need from the seller?

The registration certificate, a signed sales contract, and ideally a CARFAX report.

Is a test drive mandatory?

No, but it is highly recommended. It's the best way to find hidden problems.

How do you avoid the most common types of fraud?

Always check the RDPRM, compare the VIN with the documents, and ask for proof of maintenance.

What should I do if a problem is discovered after the purchase?

Contact the seller quickly. In case of hidden defect, you may be able to file a legal complaint.

Conclusion

Buying a used car in Quebec should not be done lightly. Thanks to this Complete checklist, you now know how to check the documents, analyze the history, inspect the vehicle and secure the transaction.

A small investment in time and verification will save you from major financial and legal hassles. Before signing and paying, keep this reflex in mind: Prudence, transparency and verification.
