1998 Lotus Esprit — MOT failures & pass rate
The 1998 Lotus Esprit passed 88.3% of its 368 recorded MOT tests. That is 13.9 percentage points better than all cars of a similar age, which fail at 25.6%. Failures cluster in lighting & signalling, emissions & environmental and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (6.3%) and emissions & environmental (4.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, headlamp aim and headlamp — catalyst emissions alone was recorded 17 times.
Mileage is the strongest signal on the record: 9.7% of 0-30k cars fail, rising to 18.9% once past 90-120k.
Advisories point at the next bill rather than this one: suspension was flagged on 15.2% of tests without failing them.
The trend is improving — the fail rate fell from 12.3% in 2021 to 8.2% 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 | 15.2% | 56 |
| 2 | Brakes | 11.7% | 43 |
| 3 | Tyres | 8.7% | 32 |
| 4 | Emissions & environmental | 6.0% | 22 |
| 5 | Steering | 3.5% | 13 |
| 6 | Lighting & signalling | 3.0% | 11 |
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 | 31 | 9.7% |
| 30-60k | 186 | 10.8% |
| 60-90k | 100 | 10.0% |
| 90-120k | 37 | 18.9% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1998 Esprit
On a 1998 Esprit, lighting & signalling is what the MOT record says goes wrong most — it appeared in 6.3% of tests. Check these areas before you commit.
- Lighting & signalling (6.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (4.6% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (3.8% 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.
