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 AX is increasingly rare these days. In fact, it narrowly missed out on being filtered out of our results – only a few more than 5000 were tested in the period our data covers. In a sense the low pass rate is to be expected, given the age and rarity of the cars.
As you’d expect the lower mileage cars have higher pass rates, and those with higher mileages start to fail as things wear out and need attention.
