1993 Toyota Corolla — MOT failures & pass rate
1,394 MOT tests on the 1993 Toyota Corolla are in this dataset, and 77.3% of them passed. That is effectively the same as small family cars of a similar age (22.2% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (10.8%) and suspension (10.3%) 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 joints — catalyst emissions alone was recorded 127 times.
A 150k+ example is materially riskier than a 30-60k one: 32.1% versus 16.8%.
Suspension is the most common advisory, noted on 34.6% of tests — work that passed today but is likely due soon.

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 | 34.6% | 483 |
| 2 | Tyres | 24.1% | 336 |
| 3 | Brakes | 21.6% | 301 |
| 4 | Emissions & environmental | 17.0% | 237 |
| 5 | Body, structure & corrosion | 13.9% | 193 |
| 6 | Other defects | 11.8% | 165 |
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 | 155 | 16.8% |
| 60-90k | 365 | 17.5% |
| 90-120k | 445 | 26.7% |
| 120-150k | 220 | 20.9% |
| 150k+ | 190 | 32.1% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Petrol | 1,347 | 22.6% |
| Diesel | 47 | 27.7% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 413 | 22.5% |
| 2022 | 348 | 24.1% |
| 2023 | 262 | 23.3% |

What to check before buying a 1993 Corolla
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 10.8% of tests. Start there.
- Lighting & signalling (10.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.3% 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 (7.0% 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.
