An MOT history is one of the most useful starting points when you are assessing a used car. It can show whether the vehicle has passed or failed previous tests, the defects recorded by testers, advisory items and mileage recorded at the time of each test.
Do not look only at the latest pass. Read backwards through several years. Repeated advisories for tyres, brakes, suspension components, corrosion or fluid leaks can tell you more than a single clean certificate. A defect that appears year after year may suggest maintenance was repeatedly postponed rather than properly resolved.
Mileage is another important signal. Compare the mileage recorded at consecutive MOT tests and look for a sensible progression. A lower figure than an earlier test, a sudden unexplained change or a long period with almost no recorded use deserves further investigation. An anomaly does not automatically prove clocking because data-entry mistakes can happen, but it gives you a specific question to raise with the seller.
Pay attention to the wording of failures and advisories. Safety-critical items and structural corrosion deserve more weight than minor wear. If a car recently failed and then passed, ask what work was completed and whether invoices are available. A pass confirms the vehicle met the test standard at that point; it is not a guarantee of its current mechanical condition.
Use the MOT record alongside the service history, invoices, current mileage and a physical inspection. Check that dates and mileages broadly support the story the seller is giving you. If something does not line up, investigate it before paying a deposit.
