## Measured asking price by model year (19 real UK listings that state a model year)

Median last-advertised asking price per model year. These are asking prices, not confirmed sale prices.

These are a different set of listings from the headline figure above: 36 of the 53 listings state a model year, and their median is £2,100. Compare a model year below against £2,100 rather than against the all-listings median.

| Model year | Median asking price | 95% confidence range | Listings |
|---|---|---|---|
| 2025 | £3,050 | £1,950 to £3,550 | 6 |
| 2021 | £2,800 | £1,650 to £4,050 | 6 |
| 2019 | £1,100 | £900 to £2,350 | 7 |

The range is a 95% confidence interval on that year's median, not the spread of listing prices. Where two years' ranges overlap, the difference between those years is not established by this data.
