1997 Fiat Barchetta — MOT failures & pass rate
The 1997 Fiat Barchetta passed 75.3% of its 377 recorded MOT tests. That is effectively the same as all cars of a similar age (25.0% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in brakes, lighting & signalling and emissions & environmental.
What the MOT record shows
One area stands out: brakes, recorded in 13.5% of tests against 7.4% for the next-worst category.
At component level the recurring items are catalyst emissions, rbt (sp) and service brake imbalance — catalyst emissions alone was recorded 28 times.
Mileage is the strongest signal on the record: 21.9% of 30-60k cars fail, rising to 32.3% once past 120-150k.
Brakes is the most common advisory, noted on 24.9% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 26.2% in 2021 to 23.2% 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 | 24.9% | 94 |
| 2 | Suspension | 23.6% | 89 |
| 3 | Tyres | 15.9% | 60 |
| 4 | Body, structure & corrosion | 10.9% | 41 |
| 5 | Emissions & environmental | 8.2% | 31 |
| 6 | Lighting & signalling | 5.8% | 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 | 114 | 21.9% |
| 60-90k | 152 | 26.3% |
| 90-120k | 58 | 22.4% |
| 120-150k | 31 | 32.3% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|

What to check before buying a 1997 Barchetta
The failure pattern for this year is specific enough to inspect against: brakes accounted for 13.5% of tests. Start there.
- Brakes (13.5% 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 (7.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (6.6% 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.
