Guide content is built around UK-market model years, factory combinations, technical documentation, manufacturer material, recalls and reputable specialist evidence. Sources are listed on the relevant guide wherever practical.
Inspection results are filtered by the vehicle specification selected by the user. We avoid adding a check to every model simply because it is common used-car advice. Where a model-year transition or modified vehicle prevents certainty, the checker says so.
Corrections should be supported by identifiable evidence. Material changes are reviewed across the guide, factory matrix and generated report so one correction does not leave contradictory advice elsewhere.
