1988 Rover Mini — MOT failures & pass rate
The 1988 Rover Mini passed 77.7% of its 819 recorded MOT tests. City cars of a similar age fail at 21.4%, so the 1988 Mini sits squarely on the average. Failures cluster in lighting & signalling, emissions & environmental and suspension.
What the MOT record shows
Lighting & signalling dominates the failure mix at 15.1% of all tests — 3.2 points clear of emissions & environmental, so it is the first thing to check.
At component level the recurring items are non catalyst emissions, headlamp aim and service brake performance — non catalyst emissions alone was recorded 102 times.
Mileage is the strongest signal on the record: 17.0% of 0-30k cars fail, rising to 21.3% once past 90-120k.
Advisories point at the next bill rather than this one: suspension was flagged on 20.4% of tests without failing them.
The trend is improving — the fail rate fell from 27.4% in 2021 to 16.6% in 2025, as the worst-kept examples leave the fleet.

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 | 20.4% | 167 |
| 2 | Emissions & environmental | 13.9% | 114 |
| 3 | Body, structure & corrosion | 9.7% | 79 |

| 5 | Tyres | 8.6% | 70 |
| 6 | Brakes | 6.7% | 55 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 30-60k | 252 | 18.6% |
| 60-90k | 337 | 27.6% |
| 90-120k | 61 | 21.3% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1988 Mini
On a 1988 Mini, lighting & signalling is what the MOT record says goes wrong most — it appeared in 15.1% of tests. Check these areas before you commit.
- 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 (12.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Suspension (7.7% 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.
