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 3.0× that share |
| The 236 models compared | 50 of 236, highest first |
| The model's own record | 655,754 tests · every year of the Ka → |
A share of tests is not a probability for your car: it counts every Ford Ka tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
