How big is the online market for car parts in Europe?
W&N has been measuring European parts e-commerce continuously for years — channel by channel, country by country. The figures below come from our own research. For every number, we state what it refers to and where it comes from.
The European online market for car parts in 2025
In calendar year 2025, car parts worth €17.4bn were sold through the online channels we cover — net sales, i.e. excluding VAT. Against 2024 that is an increase of +4.4%.
Marketplaces versus own web shops
net sales 2025 by channel group
Marketplaces are eBay, Amazon, Allegro, Kaufland and comparable platforms. B2C web shops are the own online shops of dealers, workshop chains and manufacturers. The marketplace share therefore stands at a good four euros in ten.
The largest marketplaces
net sales 2025 · share of the total market
These three platforms — eBay plus Amazon’s marketplace and retail businesses — account for 37.5% of the entire European online parts trade. Many dealers sell on a marketplace; the figure is the volume transacted through the platform, not the turnover of a single company.
The values here are net sales, so that they remain comparable with the web shops within the same market. On the two detail pages, the same channels are additionally shown as gross merchandise value (GMV), i.e. including tax — the more common measure for a marketplace. That is why the figures there are higher; it is the same market in a different unit.
The largest operators of own web shops
net sales 2025 in the operator’s own web shop, by corporate group · share of the total market
Consolidated up to the parent company: many operators run a separate domain per country, sometimes under different brands. Counted by domain, a group would fall apart into a series of small stakes — which is why the company is shown here, not the individual shop.
Not comparable with group turnover. What is shown is exclusively the turnover through these companies’ own B2C web shops. It does not include their sales via marketplaces, their B2B and wholesale business, their bricks-and-mortar business, or anything outside the product groups and countries covered here. Autodoc, for example, also generates turnover via marketplaces and in direct B2B sales — none of which is in the figure above. Anyone holding these values against a published group turnover is comparing two different things; deviations in both directions are the rule, not the error.

From the ranking to the individual competitor
- ▸Sales volume and development per shop, per legal entity and per group — including for companies that publish no figures.
- ▸Who belongs to whom: domains, entities, parent groups and buying groups in a maintained structure.
- ▸Your own position in the market, classified by country and product group.
By product group
net sales 2025, top 10 categories
Tyres and wheels are by a wide margin the largest product group in online trade — one in five euros turned over online falls to them. This is the structural difference from bricks-and-mortar parts distribution.
How this figure comes about
The market model brings together three data streams and converts them into turnover. In brief:
1 · What is collected
Continuous observation of more than 3,000 shop domains, each assigned to a company and its parent group. Plus sales on eBay — over 35 million individual data points on transactions, items and prices — as well as categorised turnover data for Amazon in the European core markets.
2 · How that becomes turnover
For shops without published figures, reach is translated into turnover: visits, adjusted for seasonality and app usage, times conversion rate, times basket value — depending on business model, size class and the purchasing power of the country. A basket of €85 in Germany corresponds to roughly €55 in Poland.
3 · What takes precedence
Where official company figures are available, they replace the model result. Where prior-year values exist, they calibrate the projection. Cross-checks are made against transaction-based sources and published financial statements.
Net sales or GMV? For dealers selling goods themselves, net sales apply: gross turnover less returns, discounts and VAT. For marketplaces, gross merchandise value (GMV) applies, i.e. the sum of all selling prices including tax. The two measures are kept separate — otherwise the same sale would be counted twice: once at the dealer, once at the platform.
Who the turnover is attributed to. A sale counts in full in the country where the shop is registered; cross-border sales are not redistributed. Covered are 2,930 online channels in 38 countries and 25 product groups of the passenger car aftermarket. For the many micro-shops below the observed domains, the model adds a statistical allowance.
It remains a market estimate on a measured data basis, not a full census. Deviations from individual annual reports are to be expected: those also contain non-digital divisions, services such as fitting, and segments outside the passenger car field. As of July 2026.

This page shows the market volume. We can break it down for you
- ▸Turnover by country, channel, product group and company — individually and in combination, across 38 countries and 25 product groups.
- ▸Updated month by month instead of once a year: you see shifts while they are happening, not a year later.
- ▸Time series going back over previous years — as a basis for planning, valuation and competitive monitoring.
How many online shops for car parts we cover
In the period June 2025 – May 2026 we recorded 3,260 B2C web shops for car parts. Behind them stand 2,205 companies — many dealers run several shops, often a separate domain per country. This is the number of shops we observe, not an estimate of the total population.
Behind every shop there is a company — and behind that, a structure
We record not only the shops but the complete corporate structures behind them: which domain belongs to which legal entity, which entity to which parent group, and which company is a member of which buying group. Only this makes it possible to quantify the online sales volume of a corporate group such as LKQ or PHE at all — and likewise what the members of a buying group add up to. Count domains and you see twenty country shops; know the structure and you see one group.
Period June 2025 – May 2026. Counted are shops under continuous reach measurement in the European countries of the survey, limited to the sectors of the parts trade.

Data basis and limits of the statement
Where the figures come from
All values stem from the ongoing research of Wolk & Nikolic After Sales Intelligence GmbH. The market model “E-Commerce Total Market” combines measured shop and marketplace data with traffic and turnover indicators to form a market estimate. The number of shops and companies comes from the continuous reach measurement of parts web shops.
What the figures are not
- The market model is an estimate on a measured data basis, not a full census.
- The turnover of the web shop operators is not comparable with their group turnover — what is shown is solely their own B2C web shop business in the product groups and countries covered.
- The shops recorded are the ones we observe, not an estimate of the total population in the market.
- All figures refer to car parts and accessories, not to vehicles.
