1990 Vauxhall Nova — MOT failures & pass rate
The 1990 Vauxhall Nova passed 83.3% of its 480 recorded MOT tests. All cars of a similar age fail 21.8% of the time, so this is 5.1pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 11.7% of tests against 6.7% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, headlamp aim and integral vehicle structure condition — component mounting prescribed areas alone was recorded 46 times.
Mileage matters less than usual here: the 1990 Nova fails 19.8% of the time in the 0-30k band and 17.1% at 90-120k, a spread of only 2.8 points.
Suspension is the most common advisory, noted on 12.9% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 20.8% in 2021 to 9.8% in 2025, as the worst-kept examples leave the fleet.

| 30-60k | 165 | 15.2% |
| 60-90k | 137 | 16.8% |
| 90-120k | 41 | 17.1% |
Trend over time

What to check before buying a 1990 Nova
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.7% of tests. Start there.
- Lighting & signalling (11.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (6.7% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (5.4% 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.
