About this data

Snapshots
Dealer and trader listings are captured daily. Monthly statistics describe the vehicles advertised in each calendar month.
Prices
All prices are asking prices in GBP. Percentiles (P10 / P50 / P90) describe the spread of asking prices across active listings — the middle 80% sits between P10 and P90.
Estimated sales
Counted as listings that disappear from the market between monthly snapshots — a proxy for vehicles sold or delisted. The most recent month has no figure yet because the following snapshot has not happened.
Market value
The sum of last-known asking prices across all active listings for the selection.
Lookback window
Statistics are anchored to the most recent populated month, so a full 12-month comparison is always available relative to the data even while the newest months are still being collected.
