2020 Peugeot 308 GT Line Puretech S/s Auto

CarHunch analysed 174 real MOT records for the 2020 Peugeot 308 GT Line Puretech S/s Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2020 Peugeot 308 GT Line is a solid performer, hitting a 91.1% first-time pass rate that sits well above the UK average of 80%—a genuine reliability plus. The 10.3% dangerous defect rate is reassuringly low, so safety concerns shouldn't deter you.

With a median mileage of just under 23,000 miles for a four-year-old car, these examples have been relatively lightly driven, which explains the modest 0.34 failures per vehicle and manageable 2.6 advisories. Get a pre-purchase inspection done anyway—focus on any suspension wear and brake components, since advisory issues tend to cluster there—but this is a car you can buy with confidence.

What to check before buying a 2020 Peugeot 308 GT Line Puretech S/s Auto

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.
