Ferrari 328 MOT pass rate & common failures
1,721 MOT tests on the Ferrari 328 (1985–2021) give it a 94.7% pass rate. All cars of a similar age fail 20.9% of the time, so this is 15.5pp better than the group it competes with. Its most common failure areas are lighting & signalling, emissions & environmental and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (3.1%) and emissions & environmental (2.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are non catalyst emissions, rear fog lamp and washers — non catalyst emissions alone was recorded 26 times.
Mileage matters less than usual here: the 328 fails 5.0% of the time in the 0-30k band and 4.8% at 60-90k, a spread of only 0.2 points.
The trend is improving — the fail rate fell from 7.7% in 2021 to 2.4% in 2025, as the worst-kept examples leave the fleet.

| 0-30k | 797 | 5.0% |
| 30-60k | 738 | 5.8% |
| 60-90k | 167 | 4.8% |

What to check before buying a Ferrari 328
- Lighting & signalling (3.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (2.1% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Visibility (1.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
