How these figures are made
Every number here is a median over live asking prices, floored so that no individual advert can be recovered from it, and dated so you can tell when it stopped being true.
What is measured
Public marketplace listings across 23 national markets, 8,328,155 of them live at the current release. A listing is re-checked individually to confirm it is still there; an advert that disappears from a search result is queued for checking, never assumed sold. The listings are re-checked nightly and the published figures are rebuilt once a day.
The disclosure floors
These are applied before publication, not when you ask, so no query can reach a figure the floors have not already been applied to.
| Rule | Value | What it prevents |
|---|---|---|
| Median floor | 20 | A median over a handful of cars is a car. |
| Quartile floor | 50 | A range says how far the edges reach, and the edges are where identifiable cars live. |
| Exact-count floor | 500 | Below it a count is published as a band of 10, so a count cannot be differenced to one advert. |
| Price rounding | EUR 250 | An exact median is an exact price somebody asked. |
| Mileage rounding | 1,000 km | An odometer reading is close to an identifier. |
Where a group is too small to publish, it is not dropped — it is pooled into a residual, so the published children plus the residual add up to their parent exactly. That is a property you can check on any figure we serve, and it is the reason a suppressed category cannot be recovered by subtraction.
Model years are bands
A single model year is published where the nameplate has at least 500 cars across all markets behind it, and a span like 2006–2012 where it does not. The boundaries are computed per nameplate and are the same in every market, which is what makes two countries comparable at all. A band spanning several years says so on every figure it produces.
The tax and charge parameters
There is no machine-readable European feed for vehicle registration tax. The catalogue behind the market pages is hand-read from national authority documents, and it is built so that being out of date is visible rather than silent:
- Every figure carries a source, and the source is checked mechanically. Each figure records the document it came from, a fingerprint of the exact bytes we fetched, and a span of text from inside it. That span is re-checked against those bytes every time the catalogue loads. A figure whose wording can no longer be found is withdrawn from publication, exactly as if we had never held it.
- Every figure carries a review date. Past it, and without a later check, a figure is shown only as a range; 90 days after that it is withdrawn entirely. Last year's rate is never reused. A charge nobody has re-checked stops answering rather than answering wrongly.
- Cited documents are re-fetched on a schedule and compared with what we verified. That can move a review date forward when nothing has changed. It can never change a figure: only a person can do that, against a document. A date that falls after a budget or a new year needs a person too, even when the page looks identical.
Which charges are covered varies by country, and no country is covered in full. Every market page states, charge by charge, what is verified, what is under review and what is not published. Where nothing is published it says so rather than showing a zero.
What this data cannot tell you
Stated here rather than discovered in a sales call. None of these is fixable by engineering, and any product claiming otherwise from listings data is overreaching:
- These are asking prices, never transaction prices. We observe that an advert stopped being listed. We do not observe that it sold, or for how much.
- There are no buyers in this data, only sellers. How many dealers list a specification is evidence about supply. It is never demand.
- There is no condition, damage, service history or accident status, in any market. Two cars with the same specification are not the same car.
- There is no trend and no seasonality yet. The data is too young for either, and a year-on-year claim from it would be an invention.
- Nothing here is a landed cost. Transport, VAT treatment, plate and administration fees and customs duty are not included. A price gap between two markets is not a margin.
- VAT is published as a rate, and a rate is not a charge. A used car bought under the dealer margin scheme carries no deductible destination VAT on the price at all; a private sale carries none; and a car under six months old or at or under 6,000 km is a new means of transport and is taxed in full whoever the parties are. Which applies is a fact about the transaction, not about the country, so this service computes no VAT anywhere.
