How useful is MOT history when buying a used car?

Data created
MOT history is useful — in two different ways that buyers often mix up. A single registration on GOV.UK shows that car’s recorded tests, advisories, and failures. Model-level MOT research on CARMOTIQ shows how thousands of similar cars performed at MOT in an age band.
What each layer can tell you
Registration history can reveal mileage gaps, repeated advisories, and recent fails on the car you are viewing. It cannot tell you whether that model type usually passes at 5–10 years. Fleet-level pass rates (built from 557 million UK tests in the wider CARMOTIQ corpus) help you shortlist models before you fall for one advert.
Neither layer proves repair cost, breakdown risk, or that you should buy. Use the brand matrix for free make-level preview research, brand hubs for model context, and credits when you need deeper CARMOTIQ defect analytics. See also research unlock credits.
Practical sequence: research the model → shortlist two finalists → view the car → check GOV.UK for that registration → inspect. MOT history is necessary; it is not sufficient alone.

Frequently asked questions
How useful is MOT history when buying a used car?
- One registration’s MOT history shows that car’s recorded tests. Model-level pass rates show how similar cars behave in an age band. Use both — neither replaces inspection.
Is CARMOTIQ a registration MOT check?
- No. CARMOTIQ is make-and-model MOT research from aggregated DVSA outcomes. Use GOV.UK for one vehicle; credits unlock deeper CARMOTIQ research tools.
