What to check before the MOT

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

Start with not working - it accounts for 33.9% of failed tests on this model.
Then check inoperative in the case of a single lamp or all lamps and has a serious fluid leak, the next two most common reasons.
The most common advisory is tread depth is below minimum requirements of 1.0mm (6.5% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 27,989 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.

Age at test	Pass rate		Tests
11-15 years	86.36%		176
16+ years	83.71%		2,375
