2018 Coleman Milne Rosedale — MOT failures & pass rate
The 2018 Coleman Milne Rosedale passed 84.6% of its 293 recorded MOT tests. Against all cars of a similar age (11.1% fail rate), the 2018 Rosedale comes out 4.3pp worse. Failures cluster in tyres, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — tyres (6.1%) and lighting & signalling (4.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, brake pads and coil spring — headlamp aim alone was recorded 16 times.
Advisories point at the next bill rather than this one: tyres was flagged on 23.9% of tests without failing them.
The trend is worsening — 9.1% of tests failed in 2021 against 17.2% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 Rosedale
On a 2018 Rosedale, tyres is what the MOT record says goes wrong most — it appeared in 6.1% of tests. Check these areas before you commit.
- Tyres (6.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Lighting & signalling (4.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.8% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
