Rates are per 100 MOT tests of class 4 vehicles (cars and light vans) at each age. Model comparisons are against all class 4 vehicles of the same ages and fuel, pooled over 2022 to 2025 tests: they are not matched on test year or on mileage. Advisory figures count pairs of consecutive MOT tests of the same vehicle: "next MOT" means its next test 300 to 500 days (about 10 to 16 months) later, and the no-advisory comparison is standardised to the advised vehicles' age bands. Repairs between MOTs and breakdowns are not in this data. How we compare
