Car Selling Scams to Avoid When Selling a Car Privately in Ontario

Selling a car privately is still the most common method for selling a vehicle, usually through platforms like Kijiji and Facebook Marketplace. It also comes with more risk than many sellers expect. When you sell privately, you are dealing with people you have never met, and not every buyer has honest intentions.
Private selling is slow and unpredictable at the best of times. You spend weeks answering messages, scheduling test drives, and waiting on buyers who never show. Private sales also come with a real risk of fraud. In our State of Car-Selling survey, 37% of private sellers who had a negative experience pointed to scams or fraud as the reason why. Knowing the scams before you start the sales process is the best way to protect yourself.
Key takeaways
Some of the most common car selling scams are the overpayment scam, the dirty oil (engine sabotage) scam, the fraudulent history report, and fake e-transfer or bank draft payments.
Private selling also carries everyday risks: strangers test driving your car, sharing your home address, and potential for mistakes on the ownership transfer.
The safest way to avoid all of it is to skip the private sale and sell through a secure platform like CarDoor, which pays you directly and handles the paperwork and pickup.
What are the most common car selling scams in Ontario?
These are four common car selling scams to be aware of when selling on Kijiji or Facebook Marketplace.
Overpayment
A buyer sends a certified cheque, bank draft, or e-transfer for more than your asking price, then asks you to send the difference back claiming it was a "mistake." You return the extra money quickly, and days later the original payment bounces or is reversed.
Dirty oil (engine and tailpipe sabotage)
A group of buyers arrives to view your car, often after dark. One person keeps you busy with questions or asks to inspect the trunk while another quietly sprays oil onto the engine or pours it into the tailpipe. When the car starts, the oil burns off and produces heavy smoke, so they can claim the engine is blown and pressure you into selling for a fraction of its value.
Fraudulent history report
A buyer seems eager to close quickly, then claims they do not trust standard providers like Carfax and asks you to buy a vehicle history report through a specific link they send. The link is a fake site that steals your credit card details when you pay for the report. The buyer disappears, and your card information is used for fraudulent purchases.
Fake e-transfer
A buyer shows you a screen or a delayed email that appears to confirm an Interac e-Transfer has been sent, then takes the keys. The money never actually arrives in your account. Another scam similar to this is the fake bank draft: counterfeit drafts can look completely genuine and may seem to clear before the fraud is caught weeks later.
What additional risks come with selling a car privately?
The scams above get the most attention, but the everyday risks of dealing with strangers are just as real.
Test drives put a stranger behind the wheel of your car with you in it. Checking a valid driver's licence first helps, but you are still trusting someone you just met with your car and overall safety.
Your home address is personal information. Sharing it with strangers so they can see the car invites people you know nothing about to your door, and meeting late in the evening in public carries its own safety concerns.
Paperwork is easy to get wrong. Selling a car in Ontario involves a bill of sale, a Used Vehicle Information Package, and the transfer of ownership. A mistake on the transfer can leave you exposed if the new owner collects tickets, or is in a collision before the paperwork is properly closed out.
How can you protect yourself from scams when selling a car?
CarDoor is a safer alternative to a private sale. You start online by sharing a few details about your car. From there, it is put in front of hundreds of verified dealers who compete to buy it, giving you an offer that reflects real market demand, without the risks and hassle associated with a private sale.
There are no strangers in your driveway and no test drives to supervise, because CarDoor facilitates the sale. When you accept, CarDoor handles the paperwork so you can be confident the transfer is completed correctly.
Payment is the part private sellers worry about most, and it is the part CarDoor makes simple. You are paid on the spot directly by CarDoor, so there is no fake payment to second-guess.
The bottom line
Selling a car privately can work, but it asks a lot of you: weeks of your time, strangers at your door, and the risk of scams like the overpayment trick, the dirty oil scam, the fraudulent history report, and fake payments. There is a better way to sell. CarDoor gives you a market-backed offer, handles the paperwork, and pays you directly, all without a single stranger in your driveway.
