Surpassing the four million half-year milestone for the first time since 2019 shows the UK’s used car market is building back momentum. That’s good news for the industry and for motorists who benefit from more choice and affordability across a range of higher tech, cleaner vehicles, notably in the emerging electric vehicle sector. To maintain this trajectory, a thriving new car market must be delivered across the segments, along with accelerated investment into the charging network to give every driver the ability to switch.

Below is a list of the best selling used car in Q2 2025.
