Optare Solo M850 (2003)
2003 Optare Solo M850
CarHunch analysed 133 real MOT records for the 2003 Optare Solo M850. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 2003 Optare Solo M850 is a troubling proposition for buyers: only 6.8% pass on their first MOT attempt, compared to the 80% UK average, suggesting systemic reliability issues across this cohort. The dangerous defect rate of 1.5% is mercifully low, but the fundamentally poor pass rate means this vehicle type demands serious maintenance commitment.
These are high-mileage buses with a median of 295,136 miles, which explains some wear, yet the near-total absence of failures (0.05 per vehicle) and advisories (0.2 per vehicle) tells a stranger story—vehicles aren't failing tests because they're failing them outright before reaching test standard. If you're considering one, budget for substantial remedial work upfront and expect this to be a commercial or specialist purchase, not a casual buy.
What to check before buying a 2003 Optare Solo M850
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.
