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 2.2× that share |
| The 304 models compared | 54 of 304, highest first |
| The model's own record | 283,043 tests · every year of the X5 → |
A share of tests is not a probability for your car: it counts every BMW X5 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
