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.

2019 diesel

4 MOTs

These figures come from only 4 MOT tests. 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.

2021: 0% → 2022: 100% → 2023: 100% → 2024: 100% → 2025: 100%
