What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with too high - it accounts for 32.3% of failed tests on this model.
- Then check excessively stiff or notchy and missing, the next two most common reasons.
- The most common advisory is excessively loose (4% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 7,336 miles, which is the number to compare any advert against.
Pass rate by age
