The French used car market handles a transaction volume each year that far exceeds that of new cars. Buying or selling a used vehicle between individuals remains a common operation, but the risks have not diminished. Mileage fraud, unsecured payments, incomplete documents: disputes persist and renew with the digitization of exchanges.
Mileage Fraud: An Increasing Risk Despite Digitization
The reprogramming of the odometer via software remains one of the most widespread frauds in the used car market. According to a study by the FNAA (National Federation of Automotive Agents) published in February 2026, disputes related to mileage fraud via reprogramming software are increasing, and independent mechanics are increasingly recommending the use of independent verification services.

In practical terms, a buyer cannot rely solely on the odometer reading. The maintenance booklet stamped by a professional, the service invoices, and the history of technical inspections allow for cross-referencing the declared mileage. Services like AutoVist, highlighted by industry professionals, analyze the vehicle’s history and detect inconsistencies.
For an honest private seller, keeping and providing all maintenance documents is not just a precaution: it is a selling point. A complete file reassures the buyer and speeds up the transaction.

Private Sales on Marketplaces: What Platforms Really Change
Amateur sellers today have a range of peer-to-peer platforms that simplify the selling process. Posting an ad on a mainstream marketplace takes just a few minutes, but the ease of dissemination does not address the issue of payment security or buyer reliability.
Specialized platforms offer a digital transaction with remote expertise and guaranteed payment. According to the CNPA (National Council of Automotive Professions) barometer from April 2026, these services outperform traditional sales in speed and traceability, a notable advantage for sellers in a hurry. To explore available listings and compare offers, you can visit https://www.caraffaires.com/, which brings together a wide catalog of used vehicles.
However, on general marketplaces (like Facebook Marketplace or Le Bon Coin), the responsibility for verification rests entirely on both parties. The amateur seller should frame the exchange in advance:
- Request payment by bank transfer rather than by check, as a check may bounce, and the seller will only discover this after handing over the vehicle
- Draft a detailed sales contract mentioning the mileage, the condition of the vehicle, and the absence of warranty (private sale)
- Refuse any cash transaction beyond the legal limit and prefer a handover in a public place
Legal Compliance Warranty: The April 2025 Decree Strengthens Buyer Protection
For purchases from a professional, the framework has evolved. Decree No. 2025-456 of April 12, 2025, has extended the legal compliance warranty to a minimum of 24 months for all used vehicles sold by professionals. This text, published in the Official Journal on April 13, 2025, strengthens buyer protection against non-apparent defects that manifest after purchase.
This warranty covers breakdowns and malfunctions that existed at the time of sale, even if the buyer did not detect them. The professional must cover the repair or replacement of the vehicle within this period.
For a private individual buying from a mechanic or dealer, this extended warranty provides a real safety net. However, between individuals, no legal compliance warranty applies. Only the warranty for hidden defects can be invoked, with the burden of proof resting on the buyer.
Mandatory Documents and Administrative Situation Certificate: The Checklist Not to Be Overlooked
Whether buying or selling, the transaction relies on a precise set of documents. An omission or inconsistency can block registration or reveal a lien on the vehicle.
- The administrative situation certificate (or non-lien certificate) can be downloaded for free from the ANTS website and certifies that the vehicle is neither encumbered nor subject to opposition
- The crossed gray card with the mention “sold on” followed by the exact date and time, signed by the seller, formalizes the transfer of ownership
- The technical inspection report of less than six months (for vehicles over four years old) is mandatory at the time of sale
- The Cerfa transfer certificate No. 15776 must be filled out in two copies and registered online by the seller on the ANTS website
Online registration of the transfer certificate is a step that many private sellers overlook. Without this declaration, the seller remains legally responsible for any infractions committed with the vehicle after the sale.
Used Electric and Hybrid Cars: A Segment in Transition Among Professionals
Since early 2025, sales of used electric and hybrid cars among professionals have significantly increased. This phenomenon is linked to the rapid depreciation of corporate fleets, which releases recent vehicles onto the secondary market at prices lower than new.
Certified refurbished models by the manufacturer or an approved network are preferred. For the buyer, this certification provides verification of the battery and electrical components, a technical point that field feedback identifies as the main source of concern in this segment.
The available data does not yet allow for conclusions about the long-term value retention of these used electric vehicles. Battery technology is evolving rapidly, and a well-inspected refurbished model offers better protection than a purchase without prior expertise.
Regardless of the chosen channel, the security of an automotive transaction relies on rigorous documentation and technical verification. Tools exist, from the free non-lien certificate to secure payment platforms. The regulatory framework is progressing, but individual vigilance remains the last filter against unpleasant surprises.
