Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 1.0% of tests record it — this model is 7.3× that share |
| The 282 models compared | Highest rate of any of them |
| The model's own record | 28,153 tests · every year of the 9-5 → |
A share of tests is not a probability for your car: it counts every Saab 9-5 tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
