1985 Lotus Esprit — MOT failures & pass rate
268 MOT tests on the 1985 Lotus Esprit are in this dataset, and 89.5% of them passed. All cars of a similar age fail 20.1% of the time, so this is 9.6pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (6.0%) and brakes (5.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, non catalyst emissions and rbt (sp) — headlamp aim alone was recorded 16 times.
Mileage is the strongest signal on the record: 10.9% of 0-30k cars fail, rising to 3.9% once past 60-90k.
Advisories point at the next bill rather than this one: brakes was flagged on 11.9% of tests without failing them.
The trend is improving — the fail rate fell from 15.6% in 2021 to 8.3% 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 | Brakes | 11.9% | 32 |
| 2 | Emissions & environmental | 7.1% | 19 |
| 3 | Suspension | 6.3% | 17 |
| 4 | Tyres | 6.0% | 16 |
| 5 | Steering | 3.4% | 9 |
| 6 | Body, structure & corrosion | 1.5% | 4 |
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 | 64 | 10.9% |
| 30-60k | 116 | 14.7% |
| 60-90k | 78 | 3.9% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 64 | 15.6% |
| 2022 | 56 | 10.7% |
| 2023 | 58 | 6.9% |
| 2024 | 54 | 9.3% |
| 2025 | 36 | 8.3% |
What to check before buying a 1985 Esprit
On a 1985 Esprit, lighting & signalling is what the MOT record says goes wrong most — it appeared in 6.0% of tests. Check these areas before you commit.
- Lighting & signalling (6.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (5.2% 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.
- Emissions & environmental (3.0% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
