1989 Ford Orion — MOT failures & pass rate
418 MOT tests on the 1989 Ford Orion are in this dataset, and 88.3% of them passed. That is 9.6 percentage points better than all cars of a similar age, which fail at 21.3%. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (7.2%) and suspension (5.0%) 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, headlamp aim and non catalyst emissions — component mounting prescribed areas alone was recorded 30 times.
Mileage matters less than usual here: the 1989 Orion fails 6.9% of the time in the 0-30k band and 10.9% at 90-120k, a spread of only 4.0 points.
Advisories point at the next bill rather than this one: suspension was flagged on 17.5% of tests without failing them.
The trend is improving — the fail rate fell from 13.4% in 2021 to 6.0% 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 | 17.5% | 73 |
| 2 | Body, structure & corrosion | 13.2% | 55 |
| 3 | Emissions & environmental | 10.8% | 45 |

| 5 | Tyres | 4.5% | 19 |
| 6 | Steering | 4.3% | 18 |
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 | 72 | 6.9% |
| 30-60k | 133 | 11.3% |
| 60-90k | 158 | 14.6% |
| 90-120k | 55 | 10.9% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 97 | 13.4% |
| 2022 | 89 | 15.7% |
| 2023 | 91 | 13.2% |

What to check before buying a 1989 Orion
On a 1989 Orion, lighting & signalling is what the MOT record says goes wrong most — it appeared in 7.2% of tests. Check these areas before you commit.
- Lighting & signalling (7.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.0% 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.
- Body, structure & corrosion (4.3% 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.
