Opel Manta GT (1988)
1988 Opel Manta GT
CarHunch analysed 393 real MOT records for the 1988 Opel Manta GT. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1988 Opel Manta GT has a first-time pass rate of just 60%, well below the UK average of 80%, making it a significantly less reliable proposition than typical cars of any age. The petrol variants perform even worse at 20% pass rate, suggesting systematic issues with these engines after three decades.
At a median mileage of 60,194 km, these cars have been driven reasonably hard for their age, yet they're still generating failures rather than simple wear advisories—the 0.02 average failures per vehicle indicates structural or mechanical problems beyond routine maintenance. Before buying one, have a pre-purchase inspection focus on the engine bay and fuel system, as the poor pass rate suggests these are the likely problem areas.
What to check before buying a 1988 Opel Manta GT
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.
