About our data
All analysis is based on aggregated UK DVSA MOT records. We examine hundreds of millions of MOT tests and over a billion recorded defects to identify the trends that matter most to used car buyers.
Research Reports summarise selected findings from this dataset. They are intended for general information and do not analyse individual vehicles or replace a vehicle history check.
