Porsche 928 S (1982)
1982 Porsche 928 S
CarHunch analysed 148 real MOT records for the 1982 Porsche 928 S. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 1982 Porsche 928 S has a first-time pass rate of just 47.2%, well below the UK average of 80%, making it a significantly less reliable proposition than most vehicles on the road. At 14.2% of cars having suffered a dangerous defect, these cars demand serious mechanical scrutiny before purchase.
These 928 S examples average around 101,000 miles, which is reasonable for a 40-year-old classic, but the 1.56 failures and 6.8 advisories per vehicle reveal persistent wear across multiple systems—suspension, cooling, and electrical faults crop up regularly. Before buying, have a pre-purchase inspection done by a Porsche specialist who knows the 928's common weaknesses, particularly its notorious cooling system and transmission issues.
What to check before buying a 1982 Porsche 928 S
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.
