On the safety side, the most frequently flagged dangerous fault is tyre has ply or cords exposed. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired.

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.
