A used-car listing shows you a price, a photo, and a short description. It does not show you the car's history, its mechanical condition, or whether the paperwork is in order. Those three things decide whether the purchase is sound, and all three can be checked before you pay. This guide walks through them in the order that saves the most trouble: papers first, then the car itself, then the payment.
Papers first: who owns it, and can they sell it?
Before any mechanical check, confirm the seller is entitled to sell the car and the documents match the vehicle in front of you.
Registration document (carte grise). The name on the registration should be the seller's, and the chassis number, registration number, make, model, and fuel type on the document should match the car itself, plate included. If the seller is selling on someone else's behalf, ask for written authorisation and identification for both parties, and be cautious if the story is vague. A mismatch between document and car is a reason to stop, not a detail to sort out later.
Transfer (mutation). A change of ownership has a formal process with its own documents and fees. Agree in writing who handles each step and who pays which fee, and confirm the current procedure and amounts with the relevant office or a professional before you commit — procedures and fees change, and a guide cannot substitute for the current rules. Do not accept a promise that the transfer "will be sorted later" without a written plan for how and when.
Inspection, tax, and insurance status. Ask for the current contrôle technique (roadworthiness inspection) certificate and check its date and result. Ask whether the annual tax (vignette) is paid up and whether insurance is current. Unpaid items can become your problem after the transfer, so confirm each one in writing rather than taking it on trust. Where a document is missing, treat the gap as a price and risk question, not as a formality.
The car itself: condition over cosmetics
A clean car can hide a tired machine, and a dusty one can be mechanically sound. Judge condition in a fixed order so cosmetics do not decide for you.
Outside and underneath. Walk around the car in daylight. Look for uneven panel gaps, paint that differs between panels, rust at the wheel arches and sills, and signs of repair. Look underneath where you can, and check the tyres: brand and wear should be roughly even across the axle, and the spare (if present) should be usable. Check lights, glass, wipers, and mirrors — small items that reveal how the car was kept.
Inside and electrics. Sit in every seat. Test windows, locks, air conditioning, heating, dashboard warnings, and electronics. Warning lights that stay on after starting, or that have clearly been masked, are a reason to ask questions. Check the boot, the service book if there is one, and the owner's manual. A complete service history is worth more than a polished dashboard: it shows maintenance was done, not just claimed.
Engine and fluids. With the engine cold if possible, check oil level and colour, coolant level, and any leaks underneath. Start the car and listen: uneven idling, smoke from the exhaust, or noises that change with revs all deserve a professional opinion. Check the gearbox through its positions, and the brakes and clutch for feel. If you are not qualified to judge these, bring someone who is — a pre-purchase inspection by an independent mechanic costs far less than a major repair discovered after payment.
Mileage and history. Compare the odometer reading with the service book, inspection certificates, and any past records. Inconsistent readings, missing history, or a price far below comparable cars of the same age and model are questions, not bargains, until explained. Ask directly about accidents and major repairs, and listen for whether the answer is specific or evasive.
The test drive: short, varied, and honest
Never buy without driving. A useful test drive is short but varied: town streets with stops and turns, a stretch of faster road, and a hill or a tight parking manoeuvre if you can. Notice steering pull, braking feel, gear changes, clutch bite, suspension noises over bumps, and visibility. Turn the radio off. Drive the car the way you will actually use it, not the way that flatters it. If the seller discourages a proper drive, or insists on a single quiet route, treat that as information.
Payment: the order that protects you
Agree the full price, what is included, and the payment method in writing before money moves. Do not pay in full before the transfer documents are ready and verified — stage the payment to the paperwork, so the seller's incentive and your protection move together. Prefer traceable payment over cash where possible, keep receipts for every amount, and keep copies of every document you sign and receive. If any part of the deal depends on a promise, get that promise in writing. A seller who will not put an agreement in writing is telling you something about the agreement.
A short checklist to take to the viewing
A used car bought after these checks is still a used car — it will need maintenance, and parts wear. But it is a purchase made with eyes open, at a price that reflects the car's real condition rather than its photograph. Browse current used cars on Map Syndicat and run this checklist against any listing that interests you before you commit.
- Registration matches the seller, the plates, and the chassis number.
- Transfer steps, documents, and who pays which fee are agreed in writing.
- Contrôle technique certificate is current, and tax and insurance status are confirmed.
- Service history is present and consistent with the mileage.
- A varied test drive has been done, with radio off and attention on steering, brakes, gears, and noises.
- An independent mechanic has inspected the car, or you have consciously accepted the risk of skipping that step.
- Payment is staged to the paperwork, traceable, and receipted.
