1997 Vauxhall Vectra — MOT failures & pass rate
799 MOT tests on the 1997 Vauxhall Vectra are in this dataset, and 74.0% of them passed. That is effectively the same as large family cars of a similar age (26.9% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in suspension, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — suspension (12.0%) and lighting & signalling (11.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, component mounting prescribed areas and rigid brake pipes — catalyst emissions alone was recorded 104 times.
A 150k+ example is materially riskier than a 30-60k one: 29.5% versus 16.8%.
Brakes is the most common advisory, noted on 34.9% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 25.2% in 2021 to 20.8% in 2025, as the worst-kept examples leave the fleet.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |
|---|---|---|
| 1 | Catalyst emissions | 104 |
| 2 | Component mounting prescribed areas | 57 |
| 3 | Rigid brake pipes | 49 |
| 4 | Headlamp aim | 42 |
| 5 | Prescribed areas | 34 |
| 6 | Chassis condition | 33 |
Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 34.9% | 279 |
| 2 | Suspension | 29.7% | 237 |
| 3 | Tyres | 22.1% | 177 |
| 4 | Body, structure & corrosion | 18.0% | 144 |
| 5 | Other defects | 18.0% | 144 |
| 6 | Emissions & environmental | 17.3% | 138 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 101 | 16.8% |
| 60-90k | 222 | 27.5% |
| 90-120k | 200 | 25.0% |
| 120-150k | 118 | 27.1% |
| 150k+ | 88 | 29.5% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 741 | 25.5% |
| Diesel | 58 | 32.8% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 230 | 25.2% |
| 2022 | 195 | 29.2% |
| 2023 | 154 | 26.6% |

What to check before buying a 1997 Vectra
The failure pattern for this year is specific enough to inspect against: suspension accounted for 12.0% of tests. Start there.
- Suspension (12.0% 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.
- Lighting & signalling (11.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (10.6% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
