What to check before the MOT

Built from this model's own failure record, not general advice.

Start with not working - it accounts for 45.9% of failed tests on this model.
Then check too low and excessively binding, the next two most common reasons.
The most common advisory is tread depth is below minimum requirements of 1.0mm (5.4% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 27,499 miles, which is the number to compare any advert against.

Pass rate by age
