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 2.3× that share |
| The 326 models compared | 38 of 326, highest first |
| The model's own record | 5,140,104 tests · every year of the Fiesta → |
A share of tests is not a probability for your car: it counts every Ford Fiesta tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
