1997 TVR Chimaera — MOT failures & pass rate
2,123 MOT tests on the 1997 TVR Chimaera are in this dataset, and 89.9% of them passed. All cars of a similar age fail 25.0% of the time, so this is 14.9pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and emissions & environmental.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 6.3% of tests against 2.8% for the next-worst category.
At component level the recurring items are catalyst emissions, headlamp aim and washers — catalyst emissions alone was recorded 103 times.
Mileage matters less than usual here: the 1997 Chimaera fails 8.7% of the time in the 0-30k band and 12.4% at 90-120k, a spread of only 3.7 points.
Emissions & environmental is the most common advisory, noted on 10.5% of tests — work that passed today but is likely due soon.

What to check before buying a 1997 Chimaera
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 6.3% of tests. Start there.
- Lighting & signalling (6.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.8% 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 (2.6% 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.
