1991 Mazda 323 LX

CarHunch analysed 139 real MOT records for the 1991 Mazda 323 LX. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1991 Mazda 323 LX is essentially end-of-life: only 4% pass their MOT first time, compared to the UK average of 80%, and the median CarHunch score of 55 reflects a vehicle that's fundamentally tired. The good news is that dangerous defects are rare at 1.4%, so catastrophic failures aren't the main concern—it's the cumulative wear and tear across multiple systems.

At 143,301 miles median, these cars have done proper work, yet they're remarkably trouble-free on a per-defect basis with just 0.09 failures per vehicle on average. If you're considering one, factor in that you're buying a 33-year-old car that will almost certainly need remedial work before it passes its next MOT—get a full pre-purchase inspection and budget for brake, suspension, and weathering repairs rather than assuming you've found a bargain.

What to check before buying a 1991 Mazda 323 LX

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.
