1986 Subaru 1.8 Gl

CarHunch analysed 232 real MOT records for the 1986 Subaru 1.8 Gl. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1986 Subaru 1.8 GL passes its MOT first time just 70% of the time, sitting 10 percentage points below the UK average of 80%—a meaningful gap that suggests more frequent repairs than typical classics of this era. The good news is zero dangerous defects recorded across the 232 vehicles analysed, so safety isn't a hidden concern.

These cars are averaging 69,000 miles despite being nearly 40 years old, which is remarkably low and suggests most surviving examples are cherished rather than hard-used. With almost no advisories logged and just 0.02 failures per vehicle on average, the failures that do occur are likely simple age-related wear rather than systemic problems—but plan for a pre-purchase inspection focusing on rust, gaskets, and fuel system components that plague cars of this vintage.

What to check before buying a 1986 Subaru 1.8 Gl

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.
