What the MOT record shows

Build year matters more than the headline suggests: 2006 cars pass 73.0% of the time while 2004 cars manage 69.7%, a 3.3-point spread.

One area stands out: suspension, recorded in 18.5% of tests against 13.1% for the next-worst category.

At component level the recurring items are headlamp aim, component mounting prescribed areas and rigid brake pipes — headlamp aim alone was recorded 5,113 times.

A 150k+ example is materially riskier than a 0-30k one: 34.5% versus 13.9%.

The petrol cars hold up better: 27.1% fail against 30.8% for diesel, a 3.7-point gap across 62,560 tests.

Suspension is the most common advisory, noted on 37.8% of tests — work that passed today but is likely due soon.

The trend is improving — the fail rate fell from 30.1% in 2021 to 28.1% in 2025, as the worst-kept examples leave the fleet.
