Proton Wira (2004)
2004 Proton Wira
CarHunch analysed 659 real MOT records for the 2004 Proton Wira. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2004 Proton Wira passes its MOT on the first attempt only 74.2% of the time, which is 5.8 percentage points below the UK average of 80%—a meaningful reliability shortfall that suggests you're buying into a car with genuine mechanical vulnerabilities. Nearly one in five of these vehicles (17.9%) has recorded a dangerous defect at some point, which is a material safety concern for a 20-year-old model.
At an average mileage of 43,171 miles for a 2004, these examples are relatively low-mileage survivors, yet they're still averaging over three failures per test and eight advisories each, pointing to systemic wear issues rather than isolated problems. Before committing to purchase, have a pre-buy inspection focus on the electrical and cooling systems, which typically rack up advisories on ageing Wiras, and budget for at least one round of repairs in year one.
What to check before buying a 2004 Proton Wira
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.
