Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.4% of tests record it — this model is 3.2× that share |
| The 252 models compared | 36 of 252, highest first |
| The model's own record | 366,022 tests · every year of the Corolla → |
A share of tests is not a probability for your car: it counts every Toyota Corolla tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
