What the MOT record shows
No single area dominates — visibility (5.4%) and lighting & signalling (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, brake pads and headlamp aim — wipers alone was recorded 110 times.
Condition tracks the odometer closely. Failures run at 8.8% in the 0-30k band and 16.5% in the 150k+ band, a 7.6-point spread.
Advisories point at the next bill rather than this one: tyres was flagged on 19.1% of tests without failing them.
The trend is worsening — 5.3% of tests failed in 2021 against 13.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Tourneo Custom 320 Tnium
On a 2020 Tourneo Custom 320 Tnium, visibility is what the MOT record says goes wrong most — it appeared in 5.4% of tests. Check these areas before you commit.
- Visibility (5.4% 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.
- Lighting & signalling (5.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
