1995 Ford Mustang — MOT failures & pass rate
The 1995 Ford Mustang passed 78.6% of its 346 recorded MOT tests. That is 1.8 percentage points worse than coupes & convertibles of a similar age, which fail at 19.6%. Failures cluster in brakes, lighting & signalling and emissions & environmental.
What the MOT record shows
No single area dominates — brakes (12.4%) and lighting & signalling (11.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), rigid brake pipes and service brake performance — rbt (sp) alone was recorded 26 times.
Condition tracks the odometer closely. Failures run at 20.8% in the 30-60k band and 27.3% in the 120-150k band, a 6.5-point spread.
Brakes is the most common advisory, noted on 34.7% of tests — work that passed today but is likely due soon.
The trend is worsening — 16.9% of tests failed in 2022 against 23.6% 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 | Brakes | 34.7% | 120 |
| 2 | Suspension | 18.8% | 65 |
| 3 | Tyres | 14.2% | 49 |
| 4 | Emissions & environmental | 14.2% | 49 |
| 5 | Other defects | 10.7% | 37 |
| 6 | Lighting & signalling | 8.7% | 30 |
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 | 77 | 20.8% |
| 60-90k | 128 | 17.2% |
| 90-120k | 67 | 25.4% |
| 120-150k | 33 | 27.3% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 83 | 16.9% |
| 2023 | 88 | 20.4% |
| 2024 | 78 | 21.8% |
| 2025 | 72 | 23.6% |
What to check before buying a 1995 Mustang
The failure pattern for this year is specific enough to inspect against: brakes accounted for 12.4% of tests. Start there.
- Brakes (12.4% 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 (11.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (4.9% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
