1988 Vauxhall Astra — MOT failures & pass rate
The 1988 Vauxhall Astra passed 91.3% of its 266 recorded MOT tests. Small family cars of a similar age fail 18.9% of the time, so this is 10.2pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (6.0%) and brakes (4.1%) 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 wipers — service brake performance alone was recorded 10 times.
Condition tracks the odometer closely. Failures run at 11.1% in the 0-30k band and 4.4% in the 60-90k band, a 6.7-point spread.
Body, structure & corrosion is the most common advisory, noted on 11.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 5.6% of tests failed in 2021 against 10.0% in 2025, the usual pattern as a fleet ages.

Most common specific failures
The exact components most often recorded as failures — more specific than the categories above.
| # | Failure item | Times recorded |
|---|---|---|
| 1 | Service brake performance | 10 |

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Body, structure & corrosion | 11.7% | 31 |
| 2 | Tyres | 10.9% | 29 |
| 3 | Brakes | 10.2% | 27 |
| 4 | Suspension | 8.6% | 23 |
| 5 | Emissions & environmental | 6.4% | 17 |
| 6 | Other defects | 4.5% | 12 |
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 | 63 | 11.1% |
| 30-60k | 74 | 9.5% |
| 60-90k | 68 | 4.4% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 54 | 5.6% |
| 2022 | 55 | 10.9% |
| 2023 | 53 | 13.2% |
| 2024 | 44 | 2.3% |
| 2025 | 60 | 10.0% |
What to check before buying a 1988 Astra
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.0% of tests. Start there.
- Lighting & signalling (6.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (4.1% 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.
- Body, structure & corrosion (3.4% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
