Should I check the MOT history before buying a 2020 Mercedes Benz E?

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 2020 Mercedes Benz E?

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 2020 Mercedes Benz E?

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 2020 Mercedes-Benz E passes its MOT first time at 90%, which is 10 percentage points above the UK average of 80%—a genuinely strong result that speaks to solid build quality. However, nearly a quarter of these cars (24.7%) have recorded at least one dangerous defect, which is well above the typical threshold and warrants a pre-purchase inspection by a Mercedes specialist.

These cars are running at a reasonable 33,128 miles median for their age, and the low average failure rate of 0.45 per vehicle confirms most issues are minor wear items caught as advisories (2.1 per car on average). Electric Diesel variants stand out with a 92% pass rate, while the Hybrid Electric models lag slightly at 88.5%, so fuel type does matter here—check the specific powertrain's history before committing.

The 2020 Mercedes Benz E passes its MOT first time at roughly the UK average rate (90%) — 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 90% 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 2.1 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 6,062 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.
