1996 Ford Mustang — MOT failures & pass rate
The 1996 Ford Mustang passed 81.2% of its 329 recorded MOT tests. Coupes & convertibles of a similar age fail 20.1% of the time, so this is 1.3pp better than the group it competes with. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (12.2%) 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 rbt (sp), headlamp aim and service brake performance — rbt (sp) alone was recorded 22 times.
Mileage matters less than usual here: the 1996 Mustang fails 19.4% of the time in the 30-60k band and 23.2% at 120-150k, a spread of only 3.9 points.
Advisories point at the next bill rather than this one: brakes was flagged on 25.5% of tests without failing them.
The trend is improving — the fail rate fell from 22.5% in 2022 to 14.5% 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 | Brakes | 25.5% | 84 |
| 2 | Suspension | 20.4% | 67 |
| 3 | Tyres | 15.8% | 52 |
| 4 | Other defects | 12.8% | 42 |
| 5 | Lighting & signalling | 10.3% | 34 |
| 6 | Emissions & environmental | 9.1% | 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 | 62 | 19.4% |
| 60-90k | 108 | 18.5% |
| 90-120k | 64 | 12.5% |
| 120-150k | 56 | 23.2% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2022 | 89 | 22.5% |
| 2023 | 75 | 14.7% |
| 2024 | 79 | 20.3% |

What to check before buying a 1996 Mustang
On a 1996 Mustang, brakes is what the MOT record says goes wrong most — it appeared in 12.2% of tests. Check these areas before you commit.
- Brakes (12.2% 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.
- Suspension (5.5% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
