About MOT Facts

MOT Facts is an independent data project. The UK's MOT test generates an enormous amount of useful information about which parts of which cars tend to fail — but it is published as raw, multi-gigabyte files that are hard for ordinary buyers to use. This site processes that data into clear, per-model reports.

What we believe

• Show the data, then explain it. Every page starts with real numbers.
• Be honest about limits. MOT data covers testable defects only — it is not a reliability score, and we say so on every page.
• Fewer, better pages. We don't publish pages backed by too little data; see the methodology.

How the site is produced

Every figure on this site is computed directly from the DVSA's published MOT test extracts by an open, documented pipeline — there is no manual editing of numbers and no third-party data. The current build analyses 195,394,211 class-4 MOT tests covering 2021, 2022, 2023, 2024, 2025, and the methodology sets out exactly how models are grouped, how pass rates are calculated and which pages we decline to publish because the sample is too small. The data source page records provenance and licensing.

MOT Facts is not affiliated with, endorsed by, or connected to the DVSA or any manufacturer, dealer, insurer or garage. It carries no advertising or affiliate links, so nothing on the site has a commercial reason to favour one car over another.
