Porsche Carrera Coupe Sport (1988)
1988 Porsche Carrera Coupe Sport
CarHunch analysed 150 real MOT records for the 1988 Porsche Carrera Coupe Sport. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1988 Porsche Carrera is significantly less reliable than the average UK car, with a first-time MOT pass rate of just 58.3% against the national average of 80%—meaning four in ten fail their test. Only 5.3% have ever recorded a dangerous defect, so safety isn't the primary concern, but the frequency of failures suggests ongoing mechanical issues.
These cars are typically running around 90,000 miles for their age, which is reasonable, yet they average 1.58 failures per MOT visit and 4.3 advisories—well above what you'd expect from a well-maintained classic. Before buying, insist on a full pre-purchase inspection by a Porsche specialist, as the high failure rate points to persistent problems with routine components rather than catastrophic defects.
What to check before buying a 1988 Porsche Carrera Coupe Sport
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.
