Suzuki Unknown (1984)
1984 Suzuki Unknown
CarHunch analysed 24,085 real MOT records for the 1984 Suzuki Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
These 1984 Suzukis are remarkably unreliable by modern standards, with only 50% passing their MOT on the first attempt against the UK average of 80%—meaning half fail immediately. The complete absence of dangerous defects (0%) is the only bright spot, suggesting any issues are wear-related rather than safety-critical.
The median mileage of 11,546 miles is suspiciously low for a 40-year-old vehicle, indicating most survivors in this dataset are either garage-kept classics or have incomplete service histories. With zero recorded failures or advisories per vehicle on average, the MOT data suggests these cars either don't make it to the test or the records are incomplete; if you're considering one, get a pre-purchase inspection from a specialist rather than relying on MOT history alone.
What to check before buying a 1984 Suzuki 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.
