1984 Lotus Esprit — MOT failures & pass rate
The 1984 Lotus Esprit passed 90.5% of its 264 recorded MOT tests. That is 10.1 percentage points better than all cars of a similar age, which fail at 19.5%. Failures cluster in lighting & signalling, brakes and emissions & environmental.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 7.2% of tests against 4.2% for the next-worst category.
At component level the recurring items are non catalyst emissions, headlamp and headlamp aim — non catalyst emissions alone was recorded 9 times.
Mileage matters less than usual here: the 1984 Esprit fails 8.8% of the time in the 0-30k band and 11.6% at 60-90k, a spread of only 2.8 points.
Suspension is the most common advisory, noted on 11.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 8.9% of tests failed in 2021 against 12.9% 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 | 11.7% | 31 |
| 2 | Emissions & environmental | 9.8% | 26 |
| 3 | Brakes | 5.3% | 14 |
| 4 | Lighting & signalling | 4.5% | 12 |
| 5 | Other defects | 3.8% | 10 |
| 6 | Steering | 2.6% | 7 |
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 | 68 | 8.8% |
| 30-60k | 94 | 8.5% |
| 60-90k | 95 | 11.6% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 56 | 8.9% |
| 2022 | 50 | 6.0% |
| 2023 | 69 | 14.5% |
| 2024 | 58 | 5.2% |
| 2025 | 31 | 12.9% |
What to check before buying a 1984 Esprit
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 7.2% of tests. Start there.
- 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.
- Brakes (4.2% 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 (3.4% 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.
