1997 TVR Cerbera — MOT failures & pass rate
Across 507 MOT tests, the 1997 TVR Cerbera recorded a 90.5% pass rate. Against all cars of a similar age (25.1% fail rate), the 1997 Cerbera comes out 15.6pp better. Failures cluster in lighting & signalling, emissions & environmental and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (4.5%) and emissions & environmental (4.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are catalyst emissions, washers and headlamp — catalyst emissions alone was recorded 33 times.
Mileage is the strongest signal on the record: 6.5% of 0-30k cars fail, rising to 10.6% once past 60-90k.
The trend is improving — the fail rate fell from 11.2% in 2021 to 8.2% in 2025, as the worst-kept examples leave the fleet.

| 30-60k | 305 | 9.2% |
| 60-90k | 104 | 10.6% |
Failure rate by age

What to check before buying a 1997 Cerbera
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 4.5% of tests. Start there.
- Lighting & signalling (4.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Emissions & environmental (4.3% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
- Brakes (3.2% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
