FAQs

Risk scores are calculated from real MOT failure rates sourced from DVSA bulk data, weighted by defect severity, repair frequency, mileage-adjusted failure curves, and comparison against national averages.
Data is sourced directly from the DVSA's anonymised MOT bulk data API — the same dataset used by motdata.uk and other industry sites. We aggregate millions of real test outcomes per make/model/year to calculate failure rates, then layer AI-generated analysis on top.
Not necessarily. Individual vehicles may differ. Always check a specific car's history. These are statistical trends, not guarantees of problems.

Dave's Tip

Before considering any used car purchase, check its complete MOT history before buying. It could save you thousands.

About this data

This information is compiled from DVSA published MOT failure statistics, manufacturer recalls and Technical Service Bulletins (TSBs), and widely documented engineering defects. Individual vehicles may differ — always check a specific car's history before buying.
