1990 Ford Orion — MOT failures & pass rate
Across 486 MOT tests, the 1990 Ford Orion recorded an 83.5% pass rate. Against all cars of a similar age (21.8% fail rate), the 1990 Orion comes out 5.3pp better. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
Lighting & signalling dominates the failure mix at 11.3% of all tests — 3.1 points clear of suspension, so it is the first thing to check.
At component level the recurring items are component mounting prescribed areas, headlamp aim and prescribed areas — component mounting prescribed areas alone was recorded 37 times.
Mileage matters less than usual here: the 1990 Orion fails 12.9% of the time in the 0-30k band and 16.7% at 90-120k, a spread of only 3.7 points.
Advisories point at the next bill rather than this one: suspension was flagged on 22.0% of tests without failing them.
The trend is improving — the fail rate fell from 17.3% in 2021 to 13.3% 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 | 22.0% | 107 |
| 2 | Brakes | 15.4% | 75 |
| 3 | Body, structure & corrosion | 14.2% | 69 |

| 5 | Tyres | 11.1% | 54 |
| 6 | Other defects | 9.3% | 45 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 30-60k | 131 | 21.4% |
| 60-90k | 153 | 15.7% |
| 90-120k | 54 | 16.7% |
Trend over time

What to check before buying a 1990 Orion
On a 1990 Orion, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.3% of tests. Check these areas before you commit.
- 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.
- Suspension (8.2% 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 (6.0% 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.
