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.

11 MOTs

These figures come from only 11 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.

Passed first time 100%. Typical mileage 14,556 (most between 13,007 and 20,541).

2010: 0% → 2012: 100% → 2013: 89% → 2014: 90% → 2015: 90% → 2016: 87% → 2017: 83% → 2018: 82% → 2019: 80% → 2020: 86% → 2021: 100% → 2022: 100% → 2023: 100% → 2024: 89% → 2025: 100%
