1999 Lotus Elise — MOT failures & pass rate
3,561 MOT tests on the 1999 Lotus Elise are in this dataset, and 86.6% of them passed. All cars of a similar age fail 26.0% of the time, so this is 12.7pp better than the group it competes with. Failures cluster in lighting & signalling, emissions & environmental and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (7.5%) and emissions & environmental (6.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, position lamp and headlamp aim — catalyst emissions alone was recorded 353 times.
Condition tracks the odometer closely. Failures run at 8.8% in the 0-30k band and 23.8% in the 150k+ band, a 15.1-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 13.1% of tests without failing them.
The trend is improving — the fail rate fell from 16.3% in 2021 to 11.3% 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 |

What to check before buying a 1999 Elise
On a 1999 Elise, lighting & signalling is what the MOT record says goes wrong most — it appeared in 7.5% of tests. Check these areas before you commit.
- Lighting & signalling (7.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (6.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (3.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
