What the MOT record shows

No single area dominates — suspension (6.3%) and lighting & signalling (6.0%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are shock absorbers, tread depth and wipers — shock absorbers alone was recorded 21 times.

A 60-90k example is materially riskier than a 0-30k one: 12.1% versus 2.6%.

Tyres is the most common advisory, noted on 18.3% of tests — work that passed today but is likely due soon.
