Which of the UK's 100 most common used cars have a worse record than cars their age, and which a better one. Each model's record combines two things, against cars the same age: how often it failed its 2025 MOT, which counts for 80% (see the full MOT fail-rate ranking), and how often it was involved in an injury collision in 2021 to 2024, which counts for 20% (see the full injury-collision ranking). From DVSA's MOT data and DfT's road casualty and licensing statistics.
Of the UK's 100 most common used cars, 27 have a clearly worse record than cars their age and 48 a clearly better one. The Dacia Sandero has the worst record for its age (index 132: it failed its MOT 47% more often than cars its age, and was involved in injury collisions 15% less often), and the Mazda MX-5 the best (index 60: 34% less often at the MOT, and 59% less often in injury collisions).
The record index is 100 for a model that did as well as cars its age. Each part links to the model's row on its full ranking.
Popular with taxi and private hire drivers. At least 5% of its injury collisions were recorded as a taxi or private hire car. These cars are driven much further than most, so they're involved more often. They're sold used too, so they count: Toyota Prius, Kia Niro, Toyota Auris, Toyota Corolla, Mercedes-Benz E-Class, Skoda Octavia, Volkswagen Passat.
Collision figure includes related models. The crash data names cars by DVLA's model names, and some cover more than one model, so the collision figure does too: Toyota Prius (with the Prius+), Toyota Yaris (with the Yaris Cross and GR Yaris), Toyota Aygo (with the early Aygo X), Citroën C4 (with the C4 Cactus, C4 Picasso and Grand C4 Picasso), Citroën C3 (with the C3 Picasso and early C3 Aircross), Land Rover Discovery and Discovery Sport (one figure for both). The MOT figure is the model alone.
