1980 Austin Morris Princess Hl

CarHunch analysed 10,027 real MOT records for the 1980 Austin Morris Princess Hl. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 1980 Austin Morris Princess HL is essentially unreliable by modern standards, with just a 0.1% first-time pass rate compared to the UK average of 80%—meaning nearly every example fails its MOT on the first attempt. No dangerous defects were recorded across the 10,027 vehicles analysed, which is the only bright spot, though the complete absence of recorded failures and advisories suggests these cars are simply too old and degraded to generate meaningful MOT data.

At a median mileage of 75,000 and average of 84,000 miles for a car now 44 years old, these Princesses have lived relatively gentle lives, but age rather than use is the real enemy here. Any buyer considering one should treat it as a restoration or hobby project rather than transport: expect major work on suspension, brakes, and rust before you'll pass an MOT, and budget accordingly.

What to check before buying a 1980 Austin Morris Princess Hl

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.
