1991 Peugeot 605

CarHunch analysed 187 real MOT records for the 1991 Peugeot 605. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1991 Peugeot 605 has a first-time MOT pass rate of 66%, which is 14 percentage points below the UK average of 80%, suggesting these cars are ageing poorly and typically need repair before passing. With 12.8% of vehicles having had a dangerous defect recorded, structural and safety issues are a meaningful concern for any prospective buyer.

At an average mileage of 117,187 for a 33-year-old car, these 605s have been driven hard, and they're proving it: the average vehicle racks up 1.2 failures and 3.1 advisories per test, pointing to systemic wear on brakes, suspension, and emissions systems. If you're seriously considering one, get a full pre-purchase inspection from someone familiar with 1990s Peugeots—the age and condition gap between decent examples and problem cars is substantial.

What to check before buying a 1991 Peugeot 605

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.
