Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 5.4% of tests record it — this model is 2.2× that share |
| The 368 models compared | 42 of 368, highest first |
| The model's own record | 53,684 tests · every year of the Relay → |
A share of tests is not a probability for your car: it counts every Citroen Relay tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
