App StoreMOT history is one of the most useful checks for a UK used car buyer. It shows how a vehicle performed at annual roadworthiness tests and can reveal patterns that are not obvious from a short advert. A single MOT pass does not prove a car is perfect, but the history behind that pass can tell you a lot.
When you review MOT history, look beyond the headline result. Failures, advisories, mileage entries and repeated issues can help you understand how the car has been maintained and what costs may be coming next.
Passes, failures and repairs
A pass means the vehicle met MOT requirements on the day of the test. It does not guarantee that the car is mechanically faultless. A failure shows defects that needed attention before a pass could be issued, and repeated failures can suggest poor maintenance or a seller who only repairs the car when required.
Look at how quickly failures were followed by passes. A same-day pass may mean the fault was minor or repaired immediately. Long gaps can suggest the car was off the road or repairs were delayed.
Advisories and recurring issues
Advisories are not immediate failures, but they matter. Worn tyres, corrosion, suspension play, brake wear or oil leaks can become expensive if ignored. If the same advisory appears year after year, ask whether it has actually been fixed.
Recurring advisories can also help during negotiation. They give you specific items to inspect and discuss with the seller rather than relying on general impressions.
Mileage records and warning signs
MOT mileage entries provide a useful timeline. Mileage should usually rise steadily over time. Large jumps, unexplained drops or long periods with very low use should be checked against service records, invoices and the current odometer.
Warning signs include repeated tyre or brake failures, structural corrosion, emissions failures, inconsistent mileage and advisories that are still present at the latest MOT.
Turn MOT notes into buying questions
MOT wording can look technical, but each note can become a practical question for the seller. If an advisory mentions corrosion, ask where it is and whether it has been treated. If tyres were close to the legal limit, check the current tread depth and brand. If suspension play appears more than once, listen for knocks on the test drive.
A Fast Car Check report helps bring this information together before the viewing. You can then inspect the exact areas highlighted by the MOT history instead of relying only on a quick walk around the car.
If the seller has repair receipts that match the MOT notes, keep copies with your records because they can support future resale and maintenance planning.
Quick checklist
- Check the latest MOT expiry date.
- Read failures as well as passes.
- Look for recurring advisories.
- Compare MOT mileage with the odometer and service history.
- Use MOT issues as inspection and negotiation points.
