On the safety side, the most frequently flagged dangerous fault is leaf spring to axle fixings loose to the extent that relative movement is visible o/s and n/s u bolts loose on 3rd axle. Dangerous faults cause an immediate MOT failure and mean the vehicle is not roadworthy until repaired. If you're viewing a Erf Unknown with an expired or recently passed MOT, ask the seller whether any dangerous faults were found and fixed during the last test.
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.
