Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.3% of tests record it — this model is 4.0× that share |
| The 191 models compared | 24 of 191, highest first |
| The model's own record | 275,662 tests · every year of the Mx-5 → |
A share of tests is not a probability for your car: it counts every Mazda Mx-5 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
