The MoT Files: Bottom 50 MoT performers
Our MoT data reveals a lot of information about the specifics of common MoT failure causes, whether simple bulb failures or more complex and dangerous problems, like worn out brakes or excessive rust. But what are the UK’s worst overall cars for the Mot?
We list the 50 models that have the lowest overall pass rates in the country. We’ve put a filter on so only models of which more than 5000 were tested appear, to filter out rare cars or particularly old models.
The 306 hasn’t been on sale for more than a decade, but there were still more than 100,000 put through an MoT test in the year our data covers. Rather unusually many of the suspension components have lower than average failure rates than other similarly aged cars, but other items, including lighting and brakes, bring the average pass rate down.
