What the MOT record shows
No single area dominates — visibility (4.3%) and tyres (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and service brake performance — wipers alone was recorded 56 times.
Mileage is the strongest signal on the record: 7.2% of 0-30k cars fail, rising to 16.1% once past 60-90k — 2.2× the risk.
Advisories point at the next bill rather than this one: tyres was flagged on 21.2% of tests without failing them.
