Should I check the MOT history before buying a 2015 Mercedes Benz C?

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 2015 Mercedes-Benz C passes its MOT first time at 86.6%, meaningfully better than the UK average of 80%, which is a positive sign for reliability. However, 37% of these cars have experienced a dangerous defect at some point—well above the typical threshold—so buyers should budget for potential serious issues and have any purchase inspected thoroughly by a specialist.

At 64,807 miles on average, these nine-year-old cars show typical wear for their age, yet they're averaging 1.32 failures per test and 8.1 advisories, suggesting regular maintenance is needed to keep them roadworthy. Petrol versions edge out diesels slightly (88.7% vs 86.0% pass rate), so if you're choosing between fuel types, petrol may be marginally more reliable—but either way, factor in professional servicing costs before committing to purchase.

The 2015 Mercedes Benz C has a decent first-time pass rate (86.6%), 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

✅ Good baseline reliability. A 86.6% 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 8.1 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 38,605 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.
