Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 3.7% of tests record it — this model is 2.5× that share |
| The 326 models compared | 26 of 326, highest first |
| The model's own record | 1,134,841 tests · every year of the 500 → |
A share of tests is not a probability for your car: it counts every Fiat 500 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
