Daihatsu Sirion (2007)
2007 Daihatsu Sirion
CarHunch analysed 2,421 real MOT records for the 2007 Daihatsu Sirion. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2007 Daihatsu Sirion matches the UK average pass rate at 80.1%, but that masks a significant concern: one in three of these cars (33.4%) has suffered a dangerous defect during its MOT history, well above what you'd want to see. This is a red flag that suggests structural or safety-critical issues crop up regularly on this model.
At nearly 51,000 miles on average, these Sirions are running high mileage for their age, and they're racking up an average of 3.4 failures and 22 advisories per test—suggesting chronic minor wear rather than catastrophic problems. Before buying one, get a pre-purchase inspection focused on suspension, brakes, and steering components, since the advisory count hints at accumulated wear in those areas.
What to check before buying a 2007 Daihatsu Sirion
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- ⚠️ 33.4% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
