Proton Gen 2 Gls (2005)
2005 Proton Gen 2 Gls
CarHunch analysed 142 real MOT records for the 2005 Proton Gen 2 Gls. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2005 Proton Gen 2 GLS is a notably unreliable used buy, with just 66.8% of examples passing their MOT on first attempt versus the UK average of 80%—a 13-point gap that signals consistent quality issues. Nearly one in four of these cars (23.9%) has recorded a dangerous defect at some point, which is a genuine concern for safety-conscious buyers.
These vehicles are carrying relatively modest mileage for their age at around 50,400 miles on average, yet they're still racking up an average of 2.92 failures per test and 8.3 advisories, suggesting inherent design or build weaknesses rather than wear-and-tear problems. Before committing to one, budget for immediate remedial work and factor in higher-than-average servicing costs—a pre-purchase inspection by a trusted mechanic is essential, not optional.
What to check before buying a 2005 Proton Gen 2 Gls
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.
- ⚠️ 23.9% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
