Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.1% of tests record it — this model is 3.3× that share |
| The 236 models compared | 45 of 236, highest first |
| The model's own record | 1,577,740 tests · every year of the YARIS → |
A share of tests is not a probability for your car: it counts every Toyota YARIS tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
