1997 Fiat Cinquecento — MOT failures & pass rate
Across 530 MOT tests, the 1997 Fiat Cinquecento recorded a 73.4% pass rate. That is 1.5 percentage points worse than all cars of a similar age, which fail at 25.1%. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 16.8% of tests against 11.3% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, headlamp aim and catalyst emissions — component mounting prescribed areas alone was recorded 64 times.
Mileage matters less than usual here: the 1997 Cinquecento fails 25.5% of the time in the 0-30k band and 27.5% at 90-120k, a spread of only 2.0 points.
Brakes is the most common advisory, noted on 28.9% 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 | 28.9% | 153 |
| 2 | Suspension | 26.0% | 138 |
| 3 | Emissions & environmental | 22.1% | 117 |

| 5 | Tyres | 16.4% | 87 |
| 6 | Lighting & signalling | 15.1% | 80 |
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 | 47 | 25.5% |
| 30-60k | 229 | 24.0% |
| 60-90k | 125 | 28.8% |
| 90-120k | 80 | 27.5% |
Failure rate by age
Trend over time

What to check before buying a 1997 Cinquecento
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 16.8% of tests. Start there.
- Lighting & signalling (16.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.3% 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.
- Body, structure & corrosion (9.6% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
