Choose an age and how common the car should be. We rank models by how often they fail their MOT at that age, from 130 million tests, and tell you when the differences are too small to matter.
At 7 years, any mileage, at least 5,000 tests. The Porsche 911 leads at 5.4% failing, against a national 20.6% at this age.
We rank vehicles using observed MOT outcomes. Where two models are within 2 points we mark them as level; the order between them is not meaningful.
Roadworthiness faults at test time: suspension, brakes, tyres, lights, emissions, structure, steering.
Breakdowns, engine or gearbox failures, electrical faults, recalls, warranty claims or running costs.
Each rate covers every tested car of that model and age, whatever its mileage. Typical mileage is the median reading at test.
We hold no price data, so this list is not limited to a budget. Check what your budget buys before you shortlist.

We rank vehicles using observed MOT outcomes from 130 million class 4 normal MOT tests, 2022 to 2025. It is a strong signal about how a model ages on roads in Great Britain, and a narrow one: the MOT never looks inside the engine.
Share of normal MOT tests failed at the age you choose, counting every test at that age, not only the first. Lower is better.
Models within 2 points of each other are marked level. Treat the order between them as a tie.
At least 5,000 tests at that age. Choose 20,000 or 50,000 to see only models that are common on the road.
Each card shows the most common fail item that is not a wear item, such as tyres, wiper blades or bulbs. If a model's top fail items are all wear items, we show the top one and mark it (wear).
