2014 Mercedes Benz C250 Amg Sport Edt Prem +cdi A

CarHunch analysed 120 real MOT records for the 2014 Mercedes Benz C250 Amg Sport Edt Prem +cdi A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2014 C250 AMG is a serious reliability concern: just 52% pass first time versus the UK average of 80%, meaning nearly half fail their MOT on the first attempt. With zero dangerous defects recorded across 120 vehicles, the failures aren't safety-critical, but the sheer volume of them suggests chronic mechanical issues.

At 82,600 miles on average, these cars have typical mileage for their age, so wear-and-tear alone doesn't explain the poor pass rate—this points to underlying design or maintenance problems specific to this model. The 0.52 failures per vehicle is roughly double what you'd expect from a reliable car, so budget for regular repair costs and request a full service history from any seller before committing.

What to check before buying a 2014 Mercedes Benz C250 Amg Sport Edt Prem +cdi A

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.
