Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.6% of tests record it — this model is 2.0× that share |
| The 240 models compared | 51 of 240, highest first |
| The model's own record | 191,422 tests · every year of the Slk → |
A share of tests is not a probability for your car: it counts every Mercedes-Benz Slk tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
