What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with not working - it accounts for 24.7% of failed tests on this model.
- Then check excessively binding and tread depth is below minimum requirements of 1.0mm, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (8.1% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 53,670 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.

|---|---|---|---|
| 16+ years | 84.2% | 1,525 |
