Mazda 323 Glx (1991)
1991 Mazda 323 Glx
CarHunch analysed 138 real MOT records for the 1991 Mazda 323 Glx. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
This 1991 Mazda 323 GLX is in serious trouble on the MOT. With a first-time pass rate of just 3.9% against the UK average of 80%, virtually every example you'll encounter will fail its test, and only 2.2% have ever recorded a dangerous defect—the real issue is simply age-related decay across the board.
At 115,920 miles on average, these cars are well-worn thirty-year-olds, and the 0.18 failures and 0.5 advisories per vehicle confirm they're crumbling mechanically. If you're considering one, treat the MOT as a starting point for a full pre-purchase inspection by a Mazda-familiar mechanic, because you're buying a restoration project, not a functional daily driver.
What to check before buying a 1991 Mazda 323 Glx
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.
