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.
