1992 Vauxhall Nova — MOT failures & pass rate
Across 1,087 MOT tests, the 1992 Vauxhall Nova recorded an 86.8% pass rate. That is 9.7 percentage points better than all cars of a similar age, which fail at 22.9%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 9.2% of tests against 5.8% for the next-worst category.
At component level the recurring items are headlamp aim, component mounting prescribed areas and service brake performance — headlamp aim alone was recorded 73 times.
Mileage is the strongest signal on the record: 11.6% of 0-30k cars fail, rising to 15.6% once past 90-120k.
Suspension is the most common advisory, noted on 17.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 14.8% in 2021 to 12.7% 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 |

| 5 | Emissions & environmental | 10.3% | 112 |
| 6 | Other defects | 6.3% | 68 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

What to check before buying a 1992 Nova
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 9.2% of tests. Start there.
- Lighting & signalling (9.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.8% 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.
- Suspension (4.7% 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.
