What a Brompton M3l sells for, by model year
Median asking price for each model year, measured from 61 real UK Brompton M3l listings that state a model year. These are last-advertised asking prices, not confirmed sale prices. The other 101 listings behind the typical price above don't state a model year, so they can't be placed on this table. Compare a year below against £750, the median across every listing that does state one, rather than against the £750 figure above, which pools both.
| Model year | Typical asking price | Range and typical price | Listings |
|---|---|---|---|
| 2025 | £1,200£800 to £1,750 | 7 | |
| 2022 | £850£800 to £1,000 | 15 | |
| 2021 | £800£650 to £900 | 8 | |
| 2020 | £750£650 to £950 | 10 | |
| 2019 | £1,000£1,000 to £1,100 | 11 | |
| 2018 | £800£650 to £1,100 | 10 |
Across these listings, a 2019 model typically lists at about 118% of a 2022 one, a guide to whether an older Brompton M3l is keenly priced.

The second figure is a 95% confidence range for that year’s typical price: with this many listings we can say the middle of the market sits somewhere in that span, not exactly where. Years with fewer than six listings are omitted, because below six no range can honestly be quoted at all. Where two years’ ranges overlap heavily, treat the gap between them as unproven rather than as depreciation.
