1992 Rover Mini — MOT failures & pass rate
Across 5,002 MOT tests, the 1992 Rover Mini recorded a 75.9% pass rate. That is effectively the same as city cars of a similar age (24.2% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, emissions & environmental and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 15.1% of tests against 11.0% for the next-worst category.
At component level the recurring items are non catalyst emissions, headlamp aim and catalyst emissions — non catalyst emissions alone was recorded 374 times.
Condition tracks the odometer closely. Failures run at 20.4% in the 0-30k band and 26.7% in the 90-120k band, a 6.3-point spread.
Suspension is the most common advisory, noted on 23.0% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 23.0% | 1,152 |
| 2 | Emissions & environmental | 14.3% | 715 |
| 3 | Body, structure & corrosion | 12.6% | 628 |
| 4 | Tyres | 10.4% | 519 |
| 5 | Brakes | 10.2% | 510 |
| 6 | Other defects | 5.4% | 268 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 1,018 | 20.4% |
| 30-60k | 1,662 | 24.3% |
| 60-90k | 1,921 | 25.1% |
| 90-120k | 382 | 26.7% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 1,077 | 24.7% |
| 2022 | 1,095 | 24.3% |
| 2023 | 981 | 24.6% |

What to check before buying a 1992 Mini
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 15.1% of tests. Start there.
- Lighting & signalling (15.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (11.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Suspension (9.2% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
