On the safety side, the most frequently flagged dangerous fault is tyre has a bulge, caused by separation or partial failure of its structure.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
