1996 MG Rv8 — MOT failures & pass rate
Across 292 MOT tests, the 1996 MG Rv8 recorded a 91.4% pass rate. All cars of a similar age fail 24.5% of the time, so this is 15.9pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (4.5%) and brakes (3.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, service brake imbalance and wipers — service brake performance alone was recorded 10 times.
A 60-90k example is materially riskier than a 0-30k one: 12.5% versus 7.4%.
Advisories point at the next bill rather than this one: emissions & environmental was flagged on 18.5% of tests without failing them.
The trend is worsening — 9.1% of tests failed in 2022 against 10.8% 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 | Emissions & environmental | 18.5% | 54 |
| 2 | Other defects | 9.6% | 28 |
| 3 | Steering | 5.1% | 15 |
| 4 | Lighting & signalling | 4.8% | 14 |
| 5 | Brakes | 3.8% | 11 |
| 6 | Suspension | 3.4% | 10 |
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 | 161 | 7.4% |
| 30-60k | 99 | 9.1% |
| 60-90k | 32 | 12.5% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 66 | 9.1% |
| 2023 | 66 | 6.1% |
| 2024 | 68 | 8.8% |
| 2025 | 74 | 10.8% |
What to check before buying a 1996 Rv8
On a 1996 Rv8, lighting & signalling is what the MOT record says goes wrong most — it appeared in 4.5% of tests. Check these areas before you commit.
- Lighting & signalling (4.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.1% 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.
- Visibility (2.4% 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.
