Should I check the MOT history before buying a 2005 Proton Gen 2?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

The 2005 Proton Gen-2 falls short of the UK average with a 73.1% first-time pass rate, and nearly 30% of these cars have recorded a dangerous defect at some point—a significant reliability warning for a buyer. Petrol versions show no meaningful advantage at 72.9%, so fuel type isn't a differentiator here.

These cars average around 50,000 miles for their age, which is actually reasonable, yet they still rack up 3.57 failures and 13.4 advisories per test. Before buying one, have a pre-purchase inspection focus on why nearly a third have flagged serious safety issues—it's the kind of pattern that suggests structural or systemic problems rather than isolated wear items.

The 2005 Proton Gen 2 has a below-average first-time pass rate (73.1% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 13.4 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,008 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
