Limitations
Official data: DVSA's anonymised MOT results (2023–2024), class 4 initial tests, cars at least 2.5 years old. 73 Auto analysis: the comparison rate applies the national rate of this item for each test's own age, mileage band and fuel to the Dacia tests. An MOT result reflects maintenance, mileage and how a car is used as well as its design, so this is not a measure of which make is most reliable. The wording of the defect is DVSA's.
