A mechanic in a garage is checking the data on an inspection device while standing next to the vehicle with its hood open.

Having a pre-purchase inspection carried out by an independent professional before buying a used car is important. In addition to helping you make an informed decision, it can help you avoid costly repairs and even give you more negotiating power.

Why get a pre-purchase mechanical inspection?

Some problems aren’t visible during a simple test drive or visual inspection. An examination by an independent professional can help detect issues that might otherwise go unnoticed.

Whether it’s your first car or the vehicle of your dreams, it can be tempting to close the deal quickly. However, taking the time to have the vehicle inspected remains one of the best decisions you can make before buying a car.

Pro tip

“When you finally find the vehicle you’ve been looking for, it’s normal to want to close the deal quickly. That’s exactly when an independent inspection matters most. It helps you avoid unpleasant surprises and make an informed decision based on the vehicle’s actual condition rather than your excitement in the moment.”

Even when a vehicle is sold by a dealer and an inspection sheet is provided, you can ask to have it inspected by the professional of your choice. This practice is in fact recommended by the Association des marchands de véhicules d’occasion du Québec (AMVOQ).

Who should pay for the inspection?

Usually, the buyer covers the cost, since the inspection is done for their own protection.

How much does a pre-purchase inspection cost?

On average, expect to pay between $150 and $250. The price varies depending on the depth of the examination (a simple mechanical check vs. a full inspection with a computerized report). It can also vary based on the type of motor vehicle (gas, hybrid or electric) and its size (car, SUV or pickup truck).

Where to get a vehicle inspection?

In a garage, an experienced mechanic inspects a passenger vehicle before purchase.
CAA-Quebec’s Authorized Vehicle Inspection Centres offer complete inspections. Other companies can come to you—whether at a private individual’s home or a used car dealership—to perform the inspection.

You can also go to a trusted shop or visit a CAA-Quebec Approved Auto Repair Service.

Tip: Since you’ll often have only a few hours to get the inspection done, choose a garage close to the seller.

What is checked during a pre-purchase inspection?

An experienced mechanic will perform a test drive and examine:

  • The engine
  • The suspension
  • The brakes
  • The steering
  • Fluid leaks (oil and coolant)
  • The exhaust system
  • The condition of the battery and charging system, or the state of health (SOH) of the traction battery for electric vehicles. Available only at the dealership for certain models.

Finally, they check the onboard computer using an OBD-II error code scan. This check helps detect problems that aren’t visible to the naked eye. For example, an unscrupulous seller might have turned off the “Check Engine” light without actually fixing the problem. A pre-purchase inspection can bring this type of issue to light before you complete the vehicle purchase.

Can the seller refuse an inspection?

Yes, however, a refusal is generally considered a major red flag that shouldn’t be ignored.

Can you negotiate the price after the inspection?

Yes, the inspection report is often an excellent bargaining tool for requesting a price reduction that reflects any urgent repairs needed on the used vehicle.

Does the inspection protect against a hidden defect?

Yes, to claim a hidden defect, the buyer must show that they acted as a prudent and diligent purchaser. Having the vehicle inspected is one of the best ways to demonstrate that diligence.

Does the mechanical inspection include an RDPRM check?

The mechanical inspection doesn’t include a check of the Register of Personal and Movable Real Rights (RDPRM). However, a CARFAX vehicle history report can include an option to check the RDPRM.

Before buying a vehicle, make sure to check for yourself that it’s free of debt.

A pre-purchase inspection: Buy with peace of mind

A pre-purchase inspection is a simple precaution that can save you from significant expenses. It lets you confirm your choice with greater confidence before finalizing the purchase of a used car, while limiting the risks associated with buying a used vehicle.
