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 MGF has a reputation for mechanical problems, and it tended to fare badly in contemporary reliability surveys. Head gasket failure is a common complaint, but there are also many niggles reported by owners. So you might be surprised to find that, while the MGF has a fairly low pass rate compared to the average, more recent car, it’s not all that bad at all compared to cars of the same age.
