2018 MINI Gt — MOT failures & pass rate
Across 1,924 MOT tests, the 2018 MINI Gt recorded a 91.6% pass rate. Against all cars of a similar age (10.9% fail rate), the 2018 Gt comes out 2.6pp better. Failures cluster in tyres, visibility and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.4%) and visibility (3.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and tread depth — wipers alone was recorded 69 times.
A 60-90k example is materially riskier than a 0-30k one: 11.3% versus 6.0%.
Advisories point at the next bill rather than this one: tyres was flagged on 22.4% of tests without failing them.
The trend is worsening — 5.9% of tests failed in 2021 against 10.0% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

| 0-30k | 933 | 6.0% |
| 30-60k | 814 | 10.4% |
| 60-90k | 150 | 11.3% |

What to check before buying a 2018 Gt
On a 2018 Gt, tyres is what the MOT record says goes wrong most — it appeared in 4.4% of tests. Check these areas before you commit.
- Tyres (4.4% 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.
- Visibility (3.7% 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.
- Lighting & signalling (2.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
