Alexander Dennis Unknown (2006)
2006 Alexander Dennis Unknown
CarHunch analysed 867 real MOT records for the 2006 Alexander Dennis Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2006 Alexander Dennis is a commercial bus or coach, not a private car, which explains why its 6.7% first-time MOT pass rate is catastrophically below the 80% UK average—these vehicles operate under much harder conditions and stricter commercial standards. Only 0.6% have ever had a dangerous defect on record, which is actually reassuring, but the median CarHunch score of 45 signals that routine wear and maintenance issues are endemic across the fleet.
With a median mileage of 234,289 miles for an 18-year-old vehicle, these buses have done serious work, yet they average barely 0.05 failures and 0.2 advisories per test, suggesting most issues are caught and fixed before they fail. If you're evaluating one of these for commercial use, expect it to need substantive remedial work before the next MOT—treat the pre-purchase inspection as non-negotiable, not optional.
What to check before buying a 2006 Alexander Dennis Unknown
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.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
