What to check before the MOT

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

Start with missing - it accounts for 42.5% of failed tests on this model.
Then check does not conform to the specified requirements and not working, the next two most common reasons.
Age matters here: 94.89% of 3-5 year old examples pass, against 89.83% at 6-10 years - a gap of 5.1 points.
The most common advisory is tread depth is below minimum requirements of 1.0mm (5.5% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 8,049 miles, which is the number to compare any advert against.
