2021 Mercedes Benz E 200 Sport MHEV Auto

CarHunch analysed 108 real MOT records for the 2021 Mercedes Benz E 200 Sport MHEV Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This E 200 MHEV is a significant reliability concern, with just 28.7% of vehicles passing on their first MOT compared to the UK average of 80%—that's less than one in three making it through without issues. The good news is that dangerous defects are rare at 1.8%, but the consistent failure rate suggests systematic problems rather than isolated cases.

These cars are averaging just under 31,000 miles at their first test, which is typical for three-year-old vehicles, yet the overwhelmingly low pass rate indicates the mileage isn't the culprit. With fewer than half a failure per vehicle but relatively few advisories, the faults that do arise tend to be serious enough to fail outright—so if you're considering one, insist on a thorough pre-purchase inspection by a Mercedes specialist and check the full MOT history to understand which specific systems are failing.

What to check before buying a 2021 Mercedes Benz E 200 Sport MHEV Auto

Practical pre-purchase checks for this age and model.

  • 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
  • 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
  • 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
