What to check before the MOT
Built from this model's own failure record, not general advice.
- Start with missing - it accounts for 58.5% of failed tests on this model.
- Then check tread depth is below minimum requirements of 1.0mm and not working, the next two most common reasons.
- The most common advisory is tread depth is below minimum requirements of 1.0mm (6% of all tests) - not a failure, but money you will spend sooner or later.
- Average recorded mileage at test is 6,837 miles, which is the number to compare any advert against.
Pass rate by age

| 3-5 years | 86.67% | 255 | |
| 6-10 years | 83.94% | 467 |
