FAQs
Is a 2022 Mercedes-Benz A reliable?
2022-registered examples passed 92.8% of their MOT tests (4,161 tests, 2023–2025), +1.5 points versus all UK cars registered in the same year. At roughly 4 years old with a median 21,854 miles, condition now varies car by car — always check the individual MOT history.
What mileage is too high for a 2022 A?
The median tested example shows 21,854 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.

A fault or an advisory is a quote waiting to happen. These pages set out what a garage has to tell you, what a comparable written quote should include, and what you can do if the bill is not what you agreed.

- Estimates, quotes and extra work — what a price has to cover, and when a garage may charge more than it first said.
- What a diagnostic test costs — what the fee should include, and when it should come off the repair.
- Tools — when to buy and when to skip — how to choose a diagnostic tool, and when a garage visit is cheaper than owning one.
- Choosing a garage you can check — what to verify before you hand over the keys.
- Your rights after a car repair — what to do when the work is not right, and how to put it in writing.
