Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.5% of tests record it — this model is 2.4× that share |
| The 304 models compared | 45 of 304, highest first |
| The model's own record | 59,319 tests · every year of the Master → |
A share of tests is not a probability for your car: it counts every Renault Master tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
