Everything You Need to Know About Guarantees and Steps to Buy a Car with Autofantom

Buying a car online raises a recurring concern: what happens if the vehicle has a defect after the transaction? With Autofantom, the question deserves to be asked differently. The platform structures every step, from selecting the vehicle to registration, integrating guarantees and support aimed at reducing uncertainties. Here’s what you need to understand before diving in.

Seller’s Obligation to Inform and Online Purchase

When you buy a vehicle from a professional, they have a legal obligation to inform you about the actual condition of the vehicle. This point is often underestimated by buyers, but recent case law reinforces it: a known defect or undisclosed repair history can lead to the cancellation of the sale.

In practical terms, a professional seller who fails to report a previous accident or a recurring breakdown exposes themselves to legal action. On a platform like Autofantom, this obligation translates into providing a vehicle history that can be consulted before purchase. You can find the details on the guarantees with Autofantom on Enchères Voitures, which outlines the platform’s commitments to new clients.

The dispute is not always about the breakdown itself. It often revolves around the quality of the information provided before the sale. That’s why checking a platform’s transparency on this specific point is the first reflex to have.

Legal Compliance Guarantee and Commercial Guarantee: Do Not Confuse

Two protections coexist when purchasing a vehicle, and they do not operate in the same way.

The Legal Compliance Guarantee

The legal compliance guarantee is imposed on the professional seller, with no possibility of negotiation. If the delivered vehicle does not match what was described or has a defect that you did not accept, you can demand compliance, a replacement, or a refund.

This guarantee does not depend on a contract signed with the seller. It arises directly from consumer law. It is a central lever when a vehicle has a problem at delivery or in the first months of use.

The Commercial Guarantee

The commercial guarantee, on the other hand, is a voluntary commitment from the seller or a third party. It can cover mechanical failures, specific parts, or assistance services. Its duration, scope, and exclusions vary from one contract to another.

Why does this distinction matter? Because a seller who highlights a generous commercial guarantee may give the impression that the coverage is complete. In reality, the legal guarantee protects the buyer even if the commercial guarantee has expired. The two complement each other, but one never replaces the other.

  • The legal compliance guarantee covers defects existing at the time of delivery, even if they manifest later.
  • The commercial guarantee covers breakdowns occurring during the contract period, according to the conditions defined by the seller.
  • The most common exclusions from commercial guarantees concern normal wear and tear, routine maintenance parts, and unapproved modifications.

Administrative Procedures After Purchase: What Has Changed with FranceConnect+

Buying a vehicle does not stop at payment. Registration and updating the registration certificate go through the ANTS, and the process has evolved recently.

Since February 14, 2025, the ANTS requires FranceConnect+ for sensitive vehicle-related procedures. This enhanced level of authentication replaces the old basic digital identity. In practice, you must have a certified digital identity (via La Poste or another approved provider) to finalize certain operations such as requesting a registration certificate.

This change slightly complicates the process for those who have not yet activated FranceConnect+. It is better to take care of this before purchasing the vehicle to avoid administrative blockages at the time of registration.

Concrete Steps After the Sale

  • Retrieve the signed transfer certificate from the seller and send it via the ANTS within the specified deadlines.
  • Request the registration certificate online on the ANTS website, using FranceConnect+ for enhanced authentication steps.
  • Check that the technical inspection is valid at the time of the transaction (mandatory for vehicles over four years old).
  • Obtain car insurance before taking possession of the vehicle, even for a short trip.

Transaction Security and Vehicle Verification with Autofantom

Buying online means trusting an intermediary. Autofantom structures this trust around several concrete mechanisms.

The first is the verification of the vehicle’s history. Before confirming a purchase, the buyer accesses a detailed report that includes any accidents and maintenance history. This report helps identify inconsistencies between the displayed mileage and the actual history.

The second concerns secure payment. On an intermediary platform, funds are typically held until confirmation of compliant delivery. This system reduces the risk of scams, which are common in transactions between individuals.

The third point relates to post-purchase support. A buyer who discovers an undisclosed defect has a structured complaint channel, backed by the legal obligations of the professional seller. The support does not stop at the delivery of the vehicle.

Verifying the history, securing the payment, and having a clear recourse after the sale: these three pillars define what distinguishes a structured purchase from a risky transaction. With Autofantom, every step is documented, making it easier both to make a purchase decision and to resolve any potential disputes.
