Should I check the MOT history before buying a 2004 Peugeot 406?

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.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2004 Peugeot 406 is a well-worn prospect: its 70.1% first-time pass rate trails the UK average by nearly 10 percentage points, and nearly a third of these vehicles have recorded a dangerous defect at some point. The diesel-heavy fleet (96% of cars analysed) shows no meaningful difference in reliability, passing at 69.9%, so fuel type offers no advantage here.

At an average mileage of 115,276 miles for a 20-year-old car, these 406s have been properly used, and the 4.51 average failures per test reflects cars that need real attention to stay roadworthy. With nearly 19 advisories per vehicle on average, budget for steady maintenance and have any purchase inspected by a mechanic familiar with the model's known weak points—particularly electrics and suspension components that generate those recurring failures.

The 2004 Peugeot 406 has a below-average first-time pass rate (70.1% 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 18.9 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 2,432 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.
