Before buying a used BYD, review its complete MOT history and compare previous failures, recurring advisories and recorded mileage with service records, maintenance documentation and the vehicle's current condition.

A recent MOT pass does not provide a complete picture of a vehicle's condition. Previous failures and recurring advisories can provide useful context when assessing a used vehicle.

Mileage should also be reviewed chronologically. An unusual mileage change does not automatically prove a problem, but it is something worth investigating and comparing with service documentation.

The MOT history should therefore be considered alongside service records, invoices, vehicle condition and, where appropriate, an independent inspection.
