What to check before the MOT

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

Start with missing - it accounts for 45% of failed tests on this model.
Then check not working and less than 1.0 mm thick, the next two most common reasons.
The most common advisory is excessively loose (3.2% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 7,127 miles, which is the number to compare any advert against.

Pass rate by age

A single pass rate hides the most useful thing in this data: how the same model behaves at three years old and at fifteen.
