1988 Ford Orion — MOT failures & pass rate
Across 265 MOT tests, the 1988 Ford Orion recorded an 88.3% pass rate. Against all cars of a similar age (20.9% fail rate), the 1988 Orion comes out 9.2pp better. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (6.8%) and brakes (6.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, non catalyst emissions and service brake performance — component mounting prescribed areas alone was recorded 21 times.
Condition tracks the odometer closely. Failures run at 21.7% in the 0-30k band and 9.7% in the 60-90k band, a 12.0-point spread.
Suspension is the most common advisory, noted on 16.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 14.6% in 2021 to 7.7% 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 | 16.2% | 43 |
| 2 | Tyres | 10.9% | 29 |
| 3 | Brakes | 9.4% | 25 |

| 5 | Body, structure & corrosion | 6.8% | 18 |
| 6 | Lighting & signalling | 4.2% | 11 |
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 | 46 | 21.7% |
| 30-60k | 88 | 10.2% |
| 60-90k | 103 | 9.7% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 48 | 14.6% |
| 2022 | 53 | 13.2% |
| 2023 | 57 | 12.3% |
| 2024 | 55 | 10.9% |

What to check before buying a 1988 Orion
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.8% of tests. Start there.
- Lighting & signalling (6.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.4% 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 (4.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
