1989 Leyland Roadrunner 6.12
CarHunch analysed 118 real MOT records for the 1989 Leyland Roadrunner 6.12. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1989 Leyland Roadrunner 6.12 is a genuinely reliable workhorse, with a 90% first-time pass rate that comfortably beats the UK average of 80% — and impressively, none of the 118 vehicles analysed has ever recorded a dangerous defect. The diesel variant, which accounts for 117 of the tested vehicles, maintains that same 90% pass rate with zero average failures or advisories per vehicle, suggesting these trucks are built to soldier on.
At 89,550 miles median, these vehicles show typical mileage for their age, indicating they've been reasonably used rather than abused. If you're considering one, the complete absence of failure patterns and advisory issues means you should focus your inspection on visual condition and service history rather than worrying about hidden mechanical gremlins — just verify the maintenance records are thorough.
What to check before buying a 1989 Leyland Roadrunner 6.12
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.
