1985 Volkswagen Polo — MOT failures & pass rate
The 1985 Volkswagen Polo passed 75.9% of its 340 recorded MOT tests. Against superminis of a similar age (18.7% fail rate), the 1985 Polo comes out 5.4pp worse. Failures cluster in lighting & signalling, body, structure & corrosion and suspension.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 18.2% of tests against 10.9% for the next-worst category.
At component level the recurring items are headlamp aim, position lamp and component mounting prescribed areas — headlamp aim alone was recorded 28 times.
A 90-120k example is materially riskier than a 0-30k one: 21.4% versus 34.4%.
Suspension is the most common advisory, noted on 28.2% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 21.8% in 2021 to 19.6% in 2025, as the worst-kept examples leave the fleet.

Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 0-30k | 61 | 34.4% |
| 30-60k | 96 | 21.9% |
| 60-90k | 119 | 21.0% |
| 90-120k | 42 | 21.4% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 78 | 21.8% |
| 2022 | 70 | 25.7% |
| 2023 | 80 | 28.7% |

What to check before buying a 1985 Polo
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 18.2% of tests. Start there.
- Lighting & signalling (18.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (10.9% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Suspension (8.8% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
