1999 Toyota Celica — MOT failures & pass rate
Across 2,409 MOT tests, the 1999 Toyota Celica recorded a 72.6% pass rate. That is 5.3 percentage points worse than coupes & convertibles of a similar age, which fail at 22.1%. Failures cluster in lighting & signalling, emissions & environmental and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (12.0%) and emissions & environmental (11.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, service brake performance and component mounting prescribed areas — catalyst emissions alone was recorded 393 times.
Mileage is the strongest signal on the record: 15.6% of 30-60k cars fail, rising to 34.1% once past 150k — 2.2× the risk.
Advisories point at the next bill rather than this one: suspension was flagged on 33.5% of tests without failing them.
The trend is worsening — 26.8% of tests failed in 2021 against 28.7% in 2025, the usual pattern as a fleet ages.

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 | 33.5% | 808 |
| 2 | Brakes | 30.8% | 741 |
| 3 | Tyres | 22.5% | 541 |
| 4 | Body, structure & corrosion | 20.5% | 493 |
| 5 | Emissions & environmental | 13.1% | 315 |
| 6 | Other defects | 12.9% | 311 |
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 | 109 | 15.6% |
| 60-90k | 405 | 21.5% |
| 90-120k | 736 | 26.5% |
| 120-150k | 588 | 28.2% |
| 150k+ | 555 | 34.1% |
Failure rate by age
Trend over time

What to check before buying a 1999 Celica
On a 1999 Celica, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.0% of tests. Check these areas before you commit.
- Lighting & signalling (12.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (11.7% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (11.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
