What the numbers say about the SEAT Mii
The number of SEAT Miis on the road is down 0.9% on a year earlier, behind the +1.5% for all cars and in line with SEAT as a whole (−1.1%). It is within 5% of its peak of 18,528 (December 2021).
Only 1 were first registered in the UK from July 2025 to June 2026, so the SEAT Mii is effectively no longer sold new here: the number on the road can only shrink as cars are scrapped, exported or taken off the road.
93% of licensed SEAT Miis are petrol, against 54% of all cars. Electric and plug-in hybrid versions make up 7.4% (all cars: 8.8%).
59% of those licensed at the end of 2025 were first used in 2015 or earlier (all cars: 44%), and 1.4% of registered SEAT Miis are SORN against 9.9% of all cars.
Of the 2,799 SEAT Miis first registered in 2015, 92% were still licensed at the end of 2025, against 86% of all cars first registered that year (73 Auto analysis; see the table below).

How old SEAT Miis on the road are
Official data from DfT table VEH0124: cars licensed and SORN at 31 December 2025 in the whole UK, by the year the car was first used (for a car imported used, that is its first use abroad). This table is annual and UK-wide, so its total (18,199 licensed) differs from the quarterly Great Britain figure.
| First used | Licensed | Share of licensed | SORN |
|---|---|---|---|
| 2021 | 1,033 | 5.7% | 7 |
| 2020 | 277 | 1.5% | 3 |
| 2019 | 1,267 | 7.0% | 13 |
| 2018 | 1,240 | 6.8% | 15 |
| 2017 | 1,437 | 7.9% | 21 |

How many SEAT Miis are still on the road
73 Auto analysis of two official tables: cars first registered in the UK each year (VEH0160) and cars of that year of first use still licensed at 31 December 2025 (VEH0124). The ratio is an indication, not a tracked cohort: imported used cars and cars exported, scrapped or declared off the road all move the figure, and years where the ratio exceeded 100% or fewer than 1,000 cars were registered are left out.
| Year | First registered | Licensed end 2025 | Still licensed | All cars |
|---|---|---|---|---|
| 2021 | 1,186 | 1,033 | 87.1% | 91.6% |
| 2019 | 1,330 | 1,267 | 95.3% | 91.3% |
| 2018 | 1,304 | 1,240 | 95.1% | 90.0% |
| 2017 | 1,530 | 1,437 | 93.9% | 88.8% |
| 2016 | 2,321 | 2,172 | 93.6% | 87.6% |

Limitations
Licensed means taxed or tax-exempt and allowed on the road at the quarter end; SORN cars are registered but declared off the road. DfT groups cars by its own “generic model” (SEAT MII), which 73 Auto maps to the SEAT Mii as named in our list-price catalogue; body styles and derivatives sold under that name are included. The Great Britain quarterly figures and the UK annual age table are separate official tables, so their totals differ slightly.
