Should I check the MOT history before buying a 2012 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.

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 2012 Mercedes-Benz E passes its MOT slightly more often than the UK average—84% versus 80%—but nearly half of these cars have recorded a dangerous defect at some point, which is a serious red flag for structural or safety-critical wear. Diesel models, which make up 94% of the cohort, pass at 83.8%, while petrol variants perform better at 86.7%, though sample sizes favour the diesel heavily.

At around 74,500 miles median, these cars are showing their age in detail: the average E-Class records 14 advisories per test, suggesting considerable wear across trim, electrics and suspension that owners will need to budget for. Check the vehicle's dangerous defect history carefully, budget for at least two repairs per MOT cycle, and have a pre-purchase inspection focus on brake and suspension integrity—not optional for a car with this damage profile.

The 2012 Mercedes Benz E has a decent first-time pass rate (84%), 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 14.2 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 19,000 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.
