1988 Vauxhall Nova — MOT failures & pass rate
The 1988 Vauxhall Nova passed 84.4% of its 572 recorded MOT tests. That is 5.4 percentage points better than all cars of a similar age, which fail at 20.9%. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (10.3%) and brakes (8.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, service brake performance and component mounting prescribed areas — headlamp aim alone was recorded 32 times.
Mileage matters less than usual here: the 1988 Nova fails 12.9% of the time in the 0-30k band and 9.1% at 90-120k, a spread of only 3.8 points.
Advisories point at the next bill rather than this one: suspension was flagged on 15.7% of tests without failing them.
The trend is improving — the fail rate fell from 18.3% in 2021 to 16.4% 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 | 15.7% | 90 |
| 2 | Body, structure & corrosion | 14.2% | 81 |
| 3 | Brakes | 13.8% | 79 |

| 5 | Tyres | 8.0% | 46 |
| 6 | Other defects | 6.6% | 38 |
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 | 132 | 12.9% |
| 30-60k | 222 | 18.0% |
| 60-90k | 155 | 18.1% |
| 90-120k | 44 | 9.1% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 142 | 18.3% |
| 2022 | 129 | 18.6% |

What to check before buying a 1988 Nova
On a 1988 Nova, lighting & signalling is what the MOT record says goes wrong most — it appeared in 10.3% of tests. Check these areas before you commit.
- Lighting & signalling (10.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (8.4% 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 (5.1% 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.
