1988 Rolls-Royce Silver Spirit — MOT failures & pass rate
Across 430 MOT tests, the 1988 Rolls-Royce Silver Spirit recorded an 86.7% pass rate. Against all cars of a similar age (20.9% fail rate), the 1988 Silver Spirit comes out 7.7pp better. Failures cluster in brakes, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — brakes (7.4%) and lighting & signalling (5.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), wipers and headlamp — rbt (sp) alone was recorded 24 times.
A 120-150k example is materially riskier than a 30-60k one: 27.1% versus 8.4%.
Suspension is the most common advisory, noted on 20.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 17.5% in 2021 to 15.6% 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 | 20.0% | 86 |
| 2 | Emissions & environmental | 18.8% | 81 |

| 5 | Steering | 8.8% | 38 |
| 6 | Body, structure & corrosion | 7.7% | 33 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 119 | 8.4% |
| 60-90k | 142 | 13.4% |
| 90-120k | 84 | 11.9% |
| 120-150k | 48 | 27.1% |
Trend over time
| Dataset year | Tests | Fail rate |

| 2021 | 97 | 17.5% |
| 2022 | 92 | 12.0% |

What to check before buying a 1988 Silver Spirit
The failure pattern for this year is specific enough to inspect against: brakes accounted for 7.4% of tests. Start there.
- Brakes (7.4% 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 (5.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (4.9% 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.
