Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 2.8% of tests record it — this model is 2.5× that share |
| The 316 models compared | 37 of 316, highest first |
| The model's own record | 86,319 tests · every year of the Colt → |
A share of tests is not a probability for your car: it counts every Mitsubishi Colt tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.
