1990 Lotus Elan — MOT failures & pass rate
The 1990 Lotus Elan passed 79.6% of its 1,437 recorded MOT tests. All cars of a similar age fail 21.8% of the time, so this is 1.4pp better than the group it competes with. Failures cluster in brakes, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — brakes (13.6%) and lighting & signalling (10.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, rbt (sp) and headlamp — service brake performance alone was recorded 142 times.
Mileage matters less than usual here: the 1990 Elan fails 22.2% of the time in the 0-30k band and 20.4% at 150k+, a spread of only 1.9 points.
Suspension is the most common advisory, noted on 25.2% of tests — work that passed today but is likely due soon.

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 | 25.2% | 362 |
| 2 | Brakes | 21.8% | 313 |
| 3 | Emissions & environmental | 9.8% | 141 |
| 4 | Body, structure & corrosion | 9.2% | 132 |
| 5 | Tyres | 9.2% | 132 |
| 6 | Other defects | 7.5% | 108 |
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 | 72 | 22.2% |
| 30-60k | 291 | 20.6% |
| 60-90k | 427 | 16.9% |
| 90-120k | 474 | 20.7% |
| 120-150k | 119 | 30.3% |
| 150k+ | 54 | 20.4% |
Trend over time

| 2021 | 288 | 20.5% |
| 2022 | 302 | 17.5% |
| 2023 | 289 | 22.1% |

What to check before buying a 1990 Elan
The failure pattern for this year is specific enough to inspect against: brakes accounted for 13.6% of tests. Start there.
- Brakes (13.6% 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.
- Lighting & signalling (10.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (5.9% 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.
