What to check before the MOT

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

Start with missing - it accounts for 60.9% of failed tests on this model.
Then check not working and too high, the next two most common reasons.
The most common advisory is less than 1.0 mm thick (4.7% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 8,329 miles, which is the number to compare any advert against.
