An individual posts an ad with low mileage, an attractive price, and impeccable photos. We reach out, get excited, pay a deposit, and the vehicle doesn’t exist. This scenario repeats across all online platforms for used car sales, and fraud techniques are becoming more sophisticated. Buying or selling a used vehicle online requires a precise method, not just caution.
AI-generated photos and fake payment links: the new frauds to be aware of
Fraudulent ads no longer look like what we used to know. Vehicle photos can be generated or edited by artificial intelligence, with a level of realism that can deceive even a careful eye. The descriptions are sometimes artificially written to appear credible as well.
The most reliable countermeasure: ask the seller for a live video of the vehicle, with a dated element (today’s newspaper, time displayed on a phone). A personalized shot taken from a specific angle that you choose is worth more than ten beautiful ad photos.
The risk doesn’t stop at the deposit. A text message or email can redirect to a copy of the classifieds website to collect banking information. Never click on a payment link received via message: open the site or app directly from your browser. This precaution eliminates the majority of phishing attempts.
On platforms like 24auto24.com, ads are structured to facilitate comparison between models and prices, allowing for quicker identification of abnormally low offers compared to the market.
Administrative situation certificate: the verification the buyer must do alone
Many buyers settle for the documents provided by the seller. The problem is that a fake seller can also provide fake documents. The administrative situation certificate can be requested for free with just the license plate, without depending on the seller.
This document reveals whether the vehicle is subject to a lien, an opposition to the transfer of the registration certificate, or a theft report. Without this independent verification, you are buying blindly, even with a complete maintenance log in front of you.
- Lien or pledge: the vehicle serves as collateral for an unpaid loan, the sale may be blocked.
- Opposition to transfer: an unpaid fine or a dispute prevents the change of ownership on the registration certificate.
- Theft report: the car will be seized by law enforcement, with no reimbursement for the buyer.
This process takes a few minutes online. It should be done systematically before going to see the vehicle, not after.
Used vehicle warranty: what changes between private sellers and professionals
Buying from a private seller and buying from a professional is not the same contract. A professional is bound by the legal warranty of conformity, which covers existing defects at the time of sale for a defined period. A private seller, on the other hand, is only subject to the warranty for hidden defects, which is more difficult to enforce because the buyer must prove that the defect existed before the sale and was concealed.
In practice, the outcomes vary on this point: some buyers achieve a favorable outcome quickly, while others engage in lengthy procedures. The choice between private and professional depends on the budget but also on the risk tolerance.
For the sale, the logic is reversed. A private seller who honestly describes the condition of the vehicle and provides all the documents (technical inspection, administrative situation certificate, maintenance log) significantly reduces the risk of disputes after the transaction.
Effective sales ad: fair price and transparency about maintenance
From the seller’s side, an ad that stands out is not the one with the prettiest photos, but the one that provides the most verifiable information. The price should match the market: compare it with the available valuations online for the same model, same year, and comparable mileage.
- Publish the report from the last technical inspection, including minor failures, rather than hiding them.
- List recent maintenance operations with dates and mileages (timing belt, brakes, tires).
- Mention visible defects: a scratch described in the ad reassures more than a “perfect” ad that raises suspicion.
- Offer a test drive and accept that an independent mechanic examines the vehicle before the sale.
A transparent ad generates fewer contacts but more serious buyers, which shortens the sales period and limits aggressive negotiations.
Mandatory documents and securing payment during the transaction
The list of documents required for the sale of a used vehicle is precise. The seller must provide the crossed-out registration certificate with the mention “sold on” followed by the date and time, the administrative situation certificate dated less than a month ago, the technical inspection dated less than six months ago (for vehicles over four years old), and the transfer declaration form.
The absence of any one of these documents blocks the transfer of the registration certificate and exposes the buyer to administrative complications that can sometimes take a long time to resolve.
For payment, bank transfer remains the most traceable method. Avoid cash beyond the legal limit and bank checks without verification with the issuing bank (a call to the official agency number, not the number printed on the check).
Whether buying or selling, the online transaction does not exempt you from a physical meeting with the vehicle. A well-written ad, independently verified documents, and secure payment form the foundation of a used car purchase or sale without unpleasant surprises.
