Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.4% of tests record it — this model is 4.0× that share |
| The 226 models compared | 19 of 226, highest first |
| The model's own record | 319,824 tests · every year of the Vito → |
A share of tests is not a probability for your car: it counts every Mercedes-Benz Vito tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
