2000 Ford Mustang — MOT failures & pass rate
The 2000 Ford Mustang passed 81.7% of its 273 recorded MOT tests. Coupes & convertibles of a similar age fail 22.3% of the time, so this is 4.0pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (12.1%) and brakes (11.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, rbt (sp) and service brake performance — headlamp aim alone was recorded 24 times.
Mileage matters less than usual here: the 2000 Mustang fails 14.1% of the time in the 30-60k band and 12.5% at 90-120k, a spread of only 1.6 points.
Brakes is the most common advisory, noted on 26.0% 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 | Brakes | 26.0% | 71 |
| 2 | Suspension | 21.6% | 59 |
| 3 | Tyres | 14.6% | 40 |
| 4 | Lighting & signalling | 12.8% | 35 |
| 5 | Steering | 8.8% | 24 |
| 6 | Other defects | 8.1% | 22 |
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 | 71 | 14.1% |
| 60-90k | 97 | 19.6% |
| 90-120k | 32 | 12.5% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 33 | 18.2% |
| 2022 | 58 | 10.3% |
| 2023 | 67 | 20.9% |
| 2024 | 64 | 21.9% |
| 2025 | 51 | 19.6% |
What to check before buying a 2000 Mustang
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 12.1% of tests. Start there.
- Lighting & signalling (12.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.0% 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.
- 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.
