Rolls Royce Unknown (1985)
1985 Rolls Royce Unknown
CarHunch analysed 129 real MOT records for the 1985 Rolls Royce Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
A 1985 Rolls Royce has a 3.1% first-time MOT pass rate—catastrophically below the UK average of 80%—though the good news is that dangerous defects are essentially absent across the 129 vehicles analysed. This isn't a reliability problem in the traditional sense; these cars are so old and low-mileage (median 58,009 miles for near-40-year-old vehicles) that most have spent decades in storage or private collections rather than regular use. Expect minor advisories rather than serious failures, but understand that you're buying a museum piece that will need professional recommissioning before it's road-legal. If you're considering one, budget for a comprehensive pre-purchase inspection and specialist recommissioning work—the MOT figures reflect dormancy, not decay.
What to check before buying a 1985 Rolls Royce 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.
