2006 Daihatsu Extol — MOT failures & pass rate
975 MOT tests on the 2006 Daihatsu Extol are in this dataset, and 72.8% of them passed. All cars of a similar age fail at 27.3%, so the 2006 Extol sits squarely on the average. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (12.8%) and suspension (11.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, catalyst emissions and integral vehicle structure condition — component mounting prescribed areas alone was recorded 239 times.
A 150k+ example is materially riskier than a 0-30k one: 24.1% versus 14.3%.
Advisories point at the next bill rather than this one: brakes was flagged on 27.5% of tests without failing them.
The trend is improving — the fail rate fell from 28.0% in 2021 to 21.6% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Brakes | 27.5% | 268 |
| 2 | Suspension | 26.8% | 261 |
| 3 | Tyres | 23.4% | 228 |
| 4 | Body, structure & corrosion | 21.5% | 210 |
| 5 | Emissions & environmental | 12.8% | 125 |
| 6 | Lighting & signalling | 9.5% | 93 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 42 | 14.3% |
| 30-60k | 198 | 23.2% |
| 60-90k | 275 | 25.1% |
| 90-120k | 303 | 30.7% |
| 120-150k | 103 | 36.9% |
| 150k+ | 54 | 24.1% |
Failure rate by age
Trend over time

What to check before buying a 2006 Extol
On a 2006 Extol, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.8% of tests. Check these areas before you commit.
- Lighting & signalling (12.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.6% 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.
- Body, structure & corrosion (10.3% 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+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
