1993 Vauxhall Nova — MOT failures & pass rate
The 1993 Vauxhall Nova passed 83.2% of its 358 recorded MOT tests. All cars of a similar age fail 23.4% of the time, so this is 6.6pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 14.2% of all tests — 6.7 points clear of suspension, so it is the first thing to check.
At component level the recurring items are headlamp aim, catalyst emissions and component mounting prescribed areas — headlamp aim alone was recorded 28 times.
Mileage matters less than usual here: the 1993 Nova fails 17.0% of the time in the 0-30k band and 18.4% at 90-120k, a spread of only 1.4 points.
Advisories point at the next bill rather than this one: suspension was flagged on 15.4% of tests without failing them.
The trend is worsening — 10.3% of tests failed in 2021 against 22.2% in 2025, the usual pattern as a fleet ages.

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 | 15.4% | 55 |
| 2 | Brakes | 14.5% | 52 |
| 3 | Body, structure & corrosion | 13.1% | 47 |

| 5 | Tyres | 8.7% | 31 |
| 6 | Other defects | 6.4% | 23 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 0-30k | 106 | 17.0% |
| 30-60k | 103 | 13.6% |
| 60-90k | 83 | 20.5% |
| 90-120k | 38 | 18.4% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1993 Nova
On a 1993 Nova, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.2% of tests. Check these areas before you commit.
- Lighting & signalling (14.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (7.5% 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.
- Brakes (7.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
