Every number in a guide comes from the same data as our reports: the known-faults database, the Real MPG figures and the service intervals. Looking for the fault list itself? That is on the common problems pages, one per model, and each guide links to its own.

12 guidesWhere these guides come from
If you used the Honest John car-by-car reviews before the site closed in 2026, this is where that kind of advice now lives. Each guide is written from the archived owner reports and model notes, our own known-faults database, the confirmed service intervals and the Real MPG figures, and every number on a guide comes from that data rather than from the text. New guides are added as they are checked.
CarAdCheck is not affiliated with Honest John or Volkswagen Financial Services. What happened to Honest John, and where each feature lives now.

The model is one decision. Reading the advert, the history and the seller are the rest.
