A car is usually one of the first things people sort out after the keys. Outside the cities you cannot really manage without one, and the car that came over on the ferry eventually needs replacing with a French-registered one.
The process is not difficult. It is just different enough from what you are used to that the ordinary assumptions do not hold. One of those differences — who you buy from — decides what happens if the car turns out to be a dud, and it is worth understanding before you hand over any money.
The four places you can buy
A main dealer. A franchised dealership selling the brand it represents. Dearest, and the used cars on the forecourt are usually prepared and come with a commercial warranty on top of your legal rights.
An independent garage. The local garage that services cars and sells a few. This is where a great many rural purchases happen, and a good one is worth finding for reasons far beyond the sale — they will service the car, put it through its test, and tell you honestly when something is not worth repairing. If you are new to a commune, ask your neighbours who they use. The answer is usually unanimous.
A mandataire. An intermediary who buys new cars in volume, often from elsewhere in Europe, and sells them at a discount. Genuine savings on a new car, and they are professionals, so your legal protections apply in full. Delivery takes longer and the car may come from abroad, so check what is included before you order.
A private seller. Cheapest, and the one that carries real risk. Read the next section before you go down this road.
The guarantee, which is the thing that matters
This is the part to understand properly, because it is the difference between a bad purchase being somebody else's problem and being entirely yours.
Buy from a professional — a dealer, a garage, a mandataire — and you get the garantie légale de conformité. On a used car it runs for 24 months, and for the first 12 months any fault that appears is presumed to have been there when you took delivery. You do not have to prove anything in that first year; the seller has to prove it was fine. After twelve months the burden shifts to you, but the protection continues to two years. A seller cannot contract out of it. Any clause in the paperwork that tries to is simply void.
Buy from a private seller and you get none of that. No conformity guarantee at all.
What you do keep, in every sale, is the garantie des vices cachés — the hidden defects rule. If the car has a serious fault that existed at the time of sale, that you could not have seen, and that makes it unfit for use, you can act. You have two years from the moment you discover the defect, not from the date of sale.
Two things people get wrong about it. "Sold as seen" written on the receipt does not protect a seller against a hidden defect — it only covers faults that were visible and that you accepted. And winning a hidden defect case against a private individual who genuinely did not know usually gets you your money back and no more, after an expert's report, letters and often a mediator. It is a real remedy and a slow one.
So: a private sale can save you a few thousand euros. A professional sale buys you two years of somebody else's responsibility. Decide which you are buying, knowingly.
What the seller must hand you
For a used car, the seller is required to give you all of this, and you should not hand over money without it.
The certificat de cession, Cerfa 15776, filled in and signed in two copies, one each. Check the chassis number on it against the car.
The carte grise, struck through and signed by the seller, with the words vendu le and the date and the time. The time matters and people forget it.
A certificat de situation administrative — the non-gage — dated less than 15 days before the sale. This proves the car is not pledged against a loan and not subject to any legal hold. A car with finance outstanding cannot be registered to you.
A contrôle technique less than six months old, for any car more than four years old. This is the French MOT. It is the seller's job to provide it, not yours.
The service book and the invoices, which are not legally required but tell you most of what you need to know.
The free check that nobody mentions
Before you buy, ask the seller for a Histovec report. It is free, it comes from the Ministry of the Interior, and it is generated by the registered keeper from the government's own records.
It shows the car's real history — previous owners, recorded mileage at each change, whether it has been declared damaged, whether it is stolen or pledged. A seller with nothing to hide produces it in two minutes. A seller who will not is telling you something.
Putting it in your name
All registration in France is done online. The préfecture has not handled this since 2017.
You apply through the national agency's site, ANTS, or you pay an approved intermediary or a licensed professional to do it for you. Many garages will, for a fee, and if your French is not yet up to a government website it is money well spent.
You have one month from the date of sale. Miss it and the fine can run to €750. In the meantime you drive on the detachable slip from the old registration document or on the temporary certificate, which is valid a month.
The cost is the car's fiscal horsepower multiplied by your region's rate, plus about €14 in fixed charges. For 2026 that rate is €60 per CV in Brittany and in Normandy, and €51 in the Pays de la Loire. A 6 CV car therefore costs around €374 in Brittany or Normandy, and about €320 in the Vendée or Loire-Atlantique.
One useful exemption: for a car more than ten years old the rate is halved.
Buying new, and the tax that bites
If you are buying new, the sticker price is not the whole story. France taxes new registrations on emissions and on weight, and the thresholds tighten every year.
For 2026 the CO2 charge starts at 108 g/km, where it is €50, and climbs steeply — at the top of the scale it reaches €80,000. There is also a weight charge from 1,500 kg, starting at €10 for each kilogram above that and rising in bands. The two together are capped at €80,000.
Electric and hydrogen cars pay neither. Non-plug-in hybrids get 100 kg knocked off the weight calculation and plug-in hybrids 200 kg, within limits. Households with three or more children can claim a reduction per child.
The practical effect is that a large, heavy petrol or diesel car is now very expensive to put on French plates for the first time, and that a modest or electric car is not. It is worth checking the figure before you commit, because it is paid at registration and it is not small.
This catches people out: imported used cars
A second-hand car being registered in France for the first time pays the malus too, with a reduction for the car's age. A car already on French plates pays nothing when it changes hands.
So a seven-year-old car bought in France and transferred to you carries no emissions tax. The same car brought in from abroad and registered here for the first time may well do. If you are thinking of bringing a car over, or buying one abroad to import, get that number before you decide — along with the tax clearance and the certificate of conformity you will need to register it.
Insure it before you drive it
Not after. French law requires the car to be insured from the moment it is yours, and the garage or the seller will expect to see the certificate.
If you are newly arrived, ask your previous insurer at home for a written statement of your claims history before you leave. French insurers will often take it into account, and starting from scratch on a French no-claims record is expensive.
The bit we do
Everything above is the sort of thing we end up helping with after a house is finished — buying the car, getting it insured, finding a garage, dealing with the registration site. It is not the building, but it is the part where people are most on their own, and it is included in what we do rather than charged for separately.
If you are at the stage of thinking about the move rather than the car, our free guide covers how building works here — the contract, the stage payments, the guarantees and the real budget. Download it here; there is nothing to pay.
Current house and land packages across Brittany, Normandy and the Vendée are listed with all-in prices, and what comes as standard is on our how we build page. If you would rather talk, book a free half-hour or send us a message on WhatsApp or by email.
The short version
From a professional you get two years of legal protection and pay more. From a private seller you get almost none and pay less. Whichever you choose, do not part with money without the certificat de cession, the struck-through carte grise with the date and time on it, a non-gage less than a fortnight old and a valid contrôle technique. Ask for the Histovec report. Register it within a month. Insure it before you drive it.
Rates, thresholds and rules checked in October 2026. Taxes on registration change every January, and the figures above are the 2026 ones. We are builders rather than motor traders or lawyers: on a disputed purchase take proper advice.
