Porsche Boxster (2020)
2020 Porsche Boxster
CarHunch analysed 482 real MOT records for the 2020 Porsche Boxster. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Porsche Boxster passes its MOT first time in 89.6% of cases, well above the UK average of 80%, and dangerous defects are rare at just 7.9%—a genuinely reassuring picture for a sports car in this age bracket. This is a well-maintained cohort that shows strong reliability credentials.
The median mileage of 16,282 miles is modest for a four-year-old car, suggesting most examples have been cherished rather than thrashed, which likely explains the low failure rate of 0.18 per vehicle. Before buying, have a pre-purchase inspection focus on the suspension and brake systems, as the average 1.1 advisories per test typically flag wear items on sports cars rather than serious faults.
What to check before buying a 2020 Porsche Boxster
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.
