1985 Vauxhall Nova — MOT failures & pass rate
379 MOT tests on the 1985 Vauxhall Nova are in this dataset, and 83.6% of them passed. Against all cars of a similar age (20.0% fail rate), the 1985 Nova comes out 3.6pp better. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (10.0%) and brakes (7.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, service brake imbalance and headlamp — service brake performance alone was recorded 21 times.
Condition tracks the odometer closely. Failures run at 13.9% in the 0-30k band and 22.4% in the 60-90k band, a 8.5-point spread.
Suspension is the most common advisory, noted on 14.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 14.9% in 2021 to 12.5% 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 | 14.2% | 54 |
| 2 | Brakes | 13.2% | 50 |
| 3 | Body, structure & corrosion | 12.7% | 48 |

| 5 | Other defects | 8.4% | 32 |
| 6 | Tyres | 7.6% | 29 |
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 | 122 | 13.9% |
| 30-60k | 120 | 15.0% |
| 60-90k | 98 | 22.4% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 74 | 14.9% |
| 2022 | 87 | 19.5% |
| 2023 | 75 | 17.3% |

What to check before buying a 1985 Nova
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 10.0% of tests. Start there.
- Lighting & signalling (10.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (7.9% 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 (6.6% 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.
