What to check before the MOT

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

Start with missing - it accounts for 33.3% of failed tests on this model.
Then check tread depth is below minimum requirements of 1.0mm and less than 1.0 mm thick, the next two most common reasons.
The most common advisory is tread depth is below minimum requirements of 1.0mm (7.8% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 9,516 miles, which is the number to compare any advert against.
