1994 TVR Chimaera — MOT failures & pass rate
822 MOT tests on the 1994 TVR Chimaera are in this dataset, and 84.7% of them passed. All cars of a similar age fail 23.8% of the time, so this is 8.5pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and emissions & environmental.
What the MOT record shows
Lighting & signalling dominates the failure mix at 9.5% of all tests — 3.0 points clear of visibility, so it is the first thing to check.
At component level the recurring items are catalyst emissions, headlamp aim and washers — catalyst emissions alone was recorded 46 times.
A 90-120k example is materially riskier than a 0-30k one: 22.1% versus 12.4%.
Advisories point at the next bill rather than this one: emissions & environmental was flagged on 14.6% of tests without failing them.
The trend is worsening — 13.9% of tests failed in 2021 against 17.0% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 30-60k | 233 | 16.3% |
| 60-90k | 302 | 12.3% |
| 90-120k | 77 | 22.1% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 166 | 13.9% |
| 2022 | 168 | 13.7% |
| 2023 | 161 | 14.9% |

What to check before buying a 1994 Chimaera
On a 1994 Chimaera, lighting & signalling is what the MOT record says goes wrong most — it appeared in 9.5% of tests. Check these areas before you commit.
- Lighting & signalling (9.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (6.5% 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.
- Emissions & environmental (4.9% 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.
