Mz Unknown (1988)
1988 Mz Unknown
CarHunch analysed 2,703 real MOT records for the 1988 Mz Unknown. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1988 MZ is essentially non-functional as a vehicle category in the MOT dataset: just 1.1% of the 2,703 examples tested achieved a first-time pass, compared to the UK average of 80%, making this one of the most reliably problematic cars on record. The complete absence of dangerous defects (0%) is almost irrelevant given that virtually every car is failing outright rather than passing with minor issues.
The median mileage of just 10,300 miles suggests most of these vehicles are either barely driven or non-operational, which explains both the zero failures and zero advisories per vehicle—the cars simply aren't being used enough to rack up meaningful wear data. Do not buy a 1988 MZ as a daily driver or regular transport; if you're considering one, treat it as a specialist restoration project and budget for comprehensive recommissioning before it will be roadworthy.
What to check before buying a 1988 Mz 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.
