Pass rate by year of first registration

Older cars fail more often, so compare a car with others of the same age. Years with very few MOTs can show extreme pass rates, even 0% or 100%, so give more weight to years with more tests.

These figures come from only 1 MOT test. With so few cars, a single pass or fail changes the percentages a lot, so treat them as a rough guide rather than a true average.

Passed first time 100%. Typical mileage 65,760 (most between 65,760 and 65,760).

2015: 100% → 2016: 0% → 2017: 100% → 2021: 100% → 2022: 100% → 2024: 100% → 2025: 100%
