Should I check the MOT history before buying a 2018 Renault Megane?

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 Renault Megane?

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 Renault Megane?

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 2018 Renault Megane passes its MOT slightly above the UK average at 82%, but there's a real concern: nearly 30% of these cars have recorded a dangerous defect at some point, which is substantially higher than typical. Petrol versions are noticeably more reliable, with an 84.3% pass rate compared to just 79.1% for diesels, so fuel choice matters here.

These Meganes are running relatively light at 31,800 miles median for their age, yet they're accumulating an average of 6.2 advisories per test, suggesting maintenance issues emerge early. With 1.12 failures per vehicle on average, electrics and suspension problems are likely culprits—so when viewing one, have an independent mechanic specifically check the electrical systems and get a full service history before committing.

The 2018 Renault Megane has a decent first-time pass rate (83.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ 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

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 6.2 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 2,034 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.
