Should I check the MOT history before buying a 2004 Proton Gen 2?

The 2004 Proton Gen-2 falls short of the UK average with a 72.6% first-time pass rate against the typical 80%, and that's compounded by a serious concern: one in three of these cars (33.8%) have recorded a dangerous defect at some point, which is well above acceptable for a buyer considering one. This combination suggests these vehicles demand careful pre-purchase inspection and a willingness to tackle safety issues head-on.

At around 50,000 miles median mileage for a 20-year-old car, these are relatively low-mileage examples, yet they're still accumulating an average of 3.75 failures and nearly 14 advisories per MOT test. The high advisory count points to age-related wear that's outpacing the reliability you'd expect, so budget for regular maintenance and have a trusted mechanic evaluate any potential purchase thoroughly before committing.

We have limited data for the 2004 Proton Gen 2 — treat the figures below as indicative rather than definitive.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.
