Opel Manta Gt/j (1982)
1982 Opel Manta Gt/j
CarHunch analysed 343 real MOT records for the 1982 Opel Manta Gt/j. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1982 Opel Manta GT/J has a first-time MOT pass rate of just 10%, dramatically below the UK average of 80%—this is a serious red flag for reliability and roadworthiness. However, the zero dangerous defect rate is a bright spot, meaning these cars aren't failing for safety-critical reasons, which suggests the failures are scattered across minor and moderate issues rather than concentrated in one problem area.
These Mantas average 81,661 miles, reasonable for a 42-year-old classic, and the zero average failures and advisories per vehicle tell us that when they do pass, they pass cleanly. If you're considering one, expect to budget for significant repair work before it's roadworthy, but focus your pre-purchase inspection on routine wear items (seals, hoses, brakes, lights) rather than worrying about fundamental structural or safety defects.
What to check before buying a 1982 Opel Manta Gt/j
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.
