Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 4.6% of tests record it — this model is 3.3× that share |
| The 318 models compared | 38 of 318, highest first |
| The model's own record | 585,817 tests · every year of the C1 → |
A share of tests is not a probability for your car: it counts every Citroen C1 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
