What this means when buying a used Daihatsu Sirion
A pass rate is a population average, not a verdict on the specific car in front of you. The average Daihatsu Sirion came to its 2025 test at 73,721 miles and 18.1 years old. Most examples tested were petrol.
The useful check is the individual car's own MOT record: how many times it has failed, what for, and whether advisories keep reappearing. A recurring advisory on corrosion, suspension or brakes tells you far more than a model-wide average, and a mileage that does not move consistently between tests is a warning in itself.
