Leyland Roadrunner 6.12 (1991)
1991 Leyland Roadrunner 6.12
CarHunch analysed 122 real MOT records for the 1991 Leyland Roadrunner 6.12. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1991 Leyland Roadrunner 6.12 is a genuinely rare survivor on UK roads—only 122 examples were tested—and it passes MOT at a rate of 1.2%, which is catastrophically below the 80% UK average. This isn't a reliability issue; it's a rarity problem: nearly every remaining example is either off the road, exempt from testing, or barely roadworthy when presented for inspection.
With a median mileage of 179,865 miles for a 33-year-old vehicle, these are heavily used survivors, yet averaging just 0.08 failures and 0.2 advisories per test suggests that when they do show up, they're relatively trouble-free on the mechanical essentials. If you're considering one, treat it as a classic or specialist purchase rather than practical transport—run a pre-purchase inspection by someone who knows 1990s light commercials, and accept that parts availability and servicing will be your real headache, not engine reliability.
What to check before buying a 1991 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.
