How we work these figures out
The DVSA publishes an anonymised record of every MOT: the make and model, the car's age, the result and what was wrong. We take the complete 2025 release for cars and light vans (class 4 tests), keep only normal tests, and count a test as an initial fail if it failed outright or passed only after a defect found in the lane was put right.
Model names in the raw data are messy. The same car appears as "COOPER", "COOPER S" and "MINI", and a BMW 3 Series hides behind badges like 320D. We fold those variants into the model family a buyer would search for, and we only publish a figure when a model has at least 12,000 tests in the year. Small samples make impressive-looking nonsense, and we'd rather show fewer numbers you can trust.
One honest caveat. These are averages across every example of a model, kind owners and careless ones alike. The car you're actually looking at has its own record, which is exactly what our free MOT check and the £5.00 report show you. Statistics say what usually happens. The history says what happened to this one. Our MOT history guide covers how to read it.
