We get to these numbers by trawling through over 1 billion MOT test results since 2004 and crunched the numbers. We remove anything to do with Tyres, as they are model independent and group together common non-model specific issues. We are trying to get to a picture of what models have what issues.

Please note: We take the data from the DVSA. This data is raw and can contain typos and spelling mistakes that garages may have entered while recording a MOT result. Specifically miss-match on names of models and makes. We are constantly cleaning the data so bear with the odd issue.

Got suggestions? We’re improving this section all the time. If you have any suggestions, please let us know.
