What the MOT record shows

No single area dominates — suspension (7.3%) 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 leaf spring, headlamp and headlamp aim — leaf spring alone was recorded 14 times.

Mileage is the strongest signal on the record: 6.7% of 0-30k cars fail, rising to 22.0% once past 60-90k — 3.3× the risk.

Suspension is the most common advisory, noted on 16.6% of tests — work that passed today but is likely due soon.
