Should I check the MOT history before buying a 2018 Peugeot 508?

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.

What corrosion should I look for when inspecting a 2018 Peugeot 508?

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.

How are tyres and brakes typically on a 2018 Peugeot 508?

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.

Moderate sample. 421 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The 2018 Peugeot 508 passes its MOT first time in 84.4% of cases, a solid 4.4 percentage points above the UK average, suggesting these cars are generally well-maintained. However, nearly one in four (23.3%) have experienced a dangerous defect at some point, which is a legitimate concern for used buyers and warrants a thorough pre-purchase inspection.

At 40,747 miles median, these vehicles are running relatively lightly for their age, yet they're averaging nearly five advisories per car—mostly minor wear items rather than serious faults, since the 0.78 average failures per vehicle is reassuringly low. Before committing to purchase, ask the seller for the full MOT history to see whether advisories are clustering in one area (like suspension or lighting), as this can reveal whether the previous owner kept up with preventive maintenance.

The 2018 Peugeot 508 passes its MOT first time at roughly the UK average rate (88.2%) — solid but worth checking this vehicle's history carefully.

⚠️ 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

✅ Good baseline reliability. A 88.2% first-time pass rate puts this well above the UK average — it's a well-sorted vehicle in this age bracket.

🔧 Expect consumable spend. An average of 4.9 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 421 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.
