1999 Proton Persona Lsi

CarHunch analysed 126 real MOT records for the 1999 Proton Persona Lsi. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 1999 Proton Persona LSI is a serious reliability concern—only 35.3% pass first time, less than half the UK average of 80%, and with a median CarHunch score of just 50, these cars are struggling badly at MOT. The good news is that dangerous defects are rare at 3.2%, so catastrophic failure isn't the issue; instead, you're looking at a vehicle that needs consistent maintenance.

At 63,797 miles on average, these cars have reasonable mileage for their age, yet they're still averaging 0.73 failures and 1.2 advisories per test—signs of aging components and deferred repairs catching up. If you're considering one, budget for an immediate pre-purchase inspection by a specialist familiar with ageing Asian imports, and expect to spend on preventative work before it gets worse.

What to check before buying a 1999 Proton Persona Lsi

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.
