What the MOT record shows

No single area dominates — lighting & signalling (4.4%) and brakes (3.3%) are close, so failures are spread across several systems rather than one weak point.

At component level the recurring items are headlamp aim, wipers and rbt (sp) — headlamp aim alone was recorded 39 times.

Brakes is the most common advisory, noted on 13.9% of tests — work that passed today but is likely due soon.

The trend is worsening — 5.4% of tests failed in 2021 against 9.8% in 2025, the usual pattern as a fleet ages.

What to check before buying a Hymer Ml

Lighting & signalling (4.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Brakes (3.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Visibility (2.7% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.

Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
