2011 Mercedes Benz Slk200 Amg Sport Ed125 Bl Cy A

CarHunch analysed 273 real MOT records for the 2011 Mercedes Benz Slk200 Amg Sport Ed125 Bl Cy A. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2011 SLK200 is in serious trouble: just 3.4% pass first time, compared to the UK average of 80%, and the petrol version sits at a catastrophic 0.4% pass rate. With zero dangerous defects recorded, the failures aren't safety-critical, but the sheer scale of repeated MOT visits signals fundamental reliability issues that make this model a genuine buyer risk.

At only 15,175 miles median mileage for a 13-year-old car, these are lightly-used vehicles, yet they're still racking up failures—suggesting age-related decay rather than wear-and-tear from high mileage. Before considering this model, get a pre-purchase inspection from a Mercedes specialist and budget heavily for remedial work; the MOT record indicates this isn't a casual fix-it situation.

What to check before buying a 2011 Mercedes Benz Slk200 Amg Sport Ed125 Bl Cy 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.
