The reflex has changed. Whereas French motorists used to go to a local junkyard or wait for a mechanic's quote for a replacement part, more and more are now opening a browser and searching directly online. By 2025, 72% of French people had already bought spare parts online or said they were ready to do so, according to industry data. And the market is proving them right: the prices of new parts have jumped dramatically in recent years – body components have increased by an average of 35%, electronic parts by 42% – naturally pushing buyers towards used parts.
This guide covers everything you need to know to confidently buy used car parts online in France: why this market is booming, how to prepare for it, how to avoid compatibility errors, and how to identify reputable sellers.
A rapidly growing market, driven by an aging vehicle fleet
The French car fleet is aging. The average age of used vehicles registered in 2025 was 11,1 years, according to the SDES (Data and Statistical Studies Service), an increase of five months compared to 2024. Sales of vehicles over 15 years old rose by 10,3%, now representing 30,4% of the used car market. Faced with soaring new car prices – the new car market declined by 5,2% in 2025 while the used car market grew by 0,7% – more and more drivers are choosing to keep their cars longer and maintain them with used parts.
The use of recycled parts is also increasing. In the first quarter of 2025, 19,6% of collision repairs included at least one recycled part, compared to 9,5% for the whole of 2020. For vehicles five years old and older, this rate even reaches 7,7% of replaced parts. According to France Casse, the most sought-after brands for used parts are Renault (18%), Peugeot (14%), Citroën (11%), Volkswagen (6,4%), and Mercedes (5,3%) – a true reflection of the French vehicle fleet.
Understanding the OEM number before starting
The most common mistake when buying auto parts online is ordering an incompatible part. This mishap costs time and money, between return shipping costs and waiting for a replacement. The solution lies in three letters: OEM.
The OEM (Original Equipment Manufacturer) number is the unique reference assigned by the manufacturer to each factory-installed part. Unlike the brand name or generic description, this code precisely identifies the part – its shape, materials, and electronic configuration. Two parts that look identical can have different OEM numbers and be incompatible due to slight differences in mounting, connectors, or electronic management specific to a particular engine version.
This number is usually engraved or printed on the label of the part being replaced. If the part is inaccessible, the Vehicle Identification Number (VIN) – this 17-character code found in field E of your vehicle registration document and visible on the driver's side of the dashboard – allows you to find the OEM part number via online catalogs from equipment manufacturers or manufacturer databases. Note that some manufacturers use their own terminology: Peugeot and Citroën use the ORGA or OPR code, while Volkswagen and its subsidiaries use the PR code.
A concrete example to understand the value of cross-referencing part numbers: the same Bosch starter (OEM part number 0986018310) is used on Citroën, Fiat, Lancia, Mitsubishi, and Peugeot vehicles. An OEM often supplies several manufacturers with the same part. This means that searching by OEM number can reveal possibilities far beyond the exact model you're looking for.
The VIN: the most reliable search tool
For searching for used parts online, the VIN is the most reliable starting point. This number encodes the vehicle's entire factory configuration – engine, transmission, trim level, and production date. It takes into account modifications made by the manufacturer during the year, which searches by model and year alone do not detect.
Most reputable platforms offer a search by VIN or registration number. Searching by license plate, very common on French websites, directly accesses vehicle data recorded in the SIV (Vehicle Registration System) and greatly facilitates the identification of compatible parts, especially for drivers less familiar with technical specifications.
Evaluating a seller: the signals to know
The online used parts market is based on two main categories of sellers: professional auto salvage yards (also called authorized end-of-life vehicle centers) and private individuals. These two channels meet distinct needs.
Online auto salvage yards offer cataloged inventory, documented traceability, and, for reputable sellers, warranties of 3 to 12 months. This is the preferred option for any critical mechanical part – engine, gearbox, ECU, safety components. Platforms that aggregate multiple listings allow you to compare prices, donor vehicle mileages, and warranty conditions all on one screen.
Private sales often offer lower prices, but without any formal guarantee. This method remains relevant for body parts, interior components, or accessories where visual inspection is possible. In such cases, always request a photo of the OEM label before making any purchase.
Some concrete signs of a reputable professional seller include: actual photos of the part (not just catalog images), the mileage and year of the donor vehicle, clearly stated return conditions, and verified reviews on third-party platforms like Trustpilot or Google. The minimum legal warranty in France is 12 months for any purchase from a professional, often extended to 24 months on the most reliable websites. Be wary of listings without return conditions or abnormally low prices on safety-critical parts: counterfeit and defective parts circulate on some platforms, with potentially serious consequences for vehicle safety.
Parts best suited for buying second-hand
Not all parts are created equal when it comes to the risk of buying used. Body components represent 40% of sales volume on the used market in 2025 and are excellent candidates: their condition is easily visible, they do not wear out mechanically, and a door or bumper in good condition from a low-mileage donor vehicle will generally offer many more years of service.
So-called "hard" mechanical parts—alternators, starters, air conditioning compressors, water pumps, gearboxes—can be excellent deals, provided you insist on a documented test and a written warranty. For a used engine, up to 180,000 km is acceptable for a well-maintained diesel, and 150,000 km for a gasoline engine. Always ask for the exact engine code and the VIN of the donor vehicle.
Avoid replacing the following parts: airbags (single-use safety components), brake pads, timing belts, cylinder head gaskets, and brake fluid hoses. These parts wear out invisibly over time, and their failure can have direct safety consequences. The cost-benefit ratio is not in their favor.
What an aggregation platform changes
Buying used parts is no longer just a matter of calling local junkyards. Platforms that aggregate the inventory of hundreds of verified dismantlers across Europe have transformed market accessibility. A driver in Bordeaux can now find a rare part for an uncommon model from a dismantler in Poland or Spain, with fast delivery and a verified seller.
Sites like OVOKO They allow you to search by VIN or OEM number across an aggregated inventory of hundreds of verified professional sellers in Europe, with documentation of the condition, mileage, and warranty conditions for each listing. This comparative transparency—comparing multiple offers for the same part number in one click, with seller reviews—represents a significant improvement over the days when you had to call each salvage yard individually, hoping to reach the right person on the phone.
Good habits to adopt before confirming the order
Before confirming a purchase of used auto parts online, a short checklist avoids most disappointments.
Verify that the OEM part number of the offered part matches that of your vehicle, ideally using your VIN. Examine the photos: they must show the actual part, not a generic image, and reveal the condition of the fasteners, connectors, and surfaces. Check the vehicle's mileage Donor and confirm that it matches the visible condition of the part. Read the return policy before paying – the legal withdrawal period is fourteen days for online purchases, but not all websites apply the same rules regarding return shipping costs. Keep the original packaging until the part is installed and tested: once installed, returns are generally impossible, even in the case of a defect.
One final precaution for expensive parts: written confirmation of compatibility with your VIN from the seller. This simple formality, which takes only a few minutes, transforms a risky purchase into a documented process. In case of a future problem, it provides concrete protection. If you have any doubts about installing a complex mechanical part, an independent mechanic will generally agree to install parts purchased by the customer – check this before buying to avoid any surprises.
The online used car parts market in France has never been as structured, transparent and accessible as it will be in 2026. For motorists who take the time to do their research, the savings are real and reliability is guaranteed.
