Smart Forfour Passion Semi Auto (2006)
2006 Smart Forfour Passion Semi Auto
CarHunch analysed 112 real MOT records for the 2006 Smart Forfour Passion Semi Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2006 Smart ForFour Passion Semi-Auto has a first-time MOT pass rate of 73.2%, which sits 6.8 points below the UK average of 80%—a meaningful gap that suggests more mechanical fragility than typical. More concerning, over a third of these cars (34.8%) have recorded a dangerous defect at some point, which is well above acceptable levels and a genuine buyer safety flag.
At an average mileage of 59,456 for an 18-year-old car, these vehicles are running closer to expectations for their age, but the real trouble shows in the failure data: each car averages 3.91 actual failures plus 18.2 advisories per test, indicating chronic issues with wear items and deteriorating systems. Before committing to one, request the full MOT history to see which components fail repeatedly—gearbox problems and suspension wear are common on this model—and budget for immediate remedial work rather than expecting a clean bill of health.
What to check before buying a 2006 Smart Forfour Passion Semi Auto
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.
