Mercedes Slk 200 Kompressor Auto (2007)
2007 Mercedes Slk 200 Kompressor Auto
CarHunch analysed 149 real MOT records for the 2007 Mercedes Slk 200 Kompressor Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2007 Mercedes SLK 200 Kompressor is a serious reliability gamble: only 24.1% pass their MOT first time, less than a third of the UK average of 80%, and petrol versions show a stark 0% pass rate on first attempt. This isn't a safe bet for a buyer prioritising dependability.
With an average of 0.39 failures per test and examples averaging around 65,000 miles, these cars are hitting real mechanical trouble relatively early in their lives. Before committing to purchase, insist on a comprehensive pre-buy inspection focused on cooling systems and engine management—the typical failure patterns for this temperamental supercharged engine—and factor in regular specialist servicing costs.
What to check before buying a 2007 Mercedes Slk 200 Kompressor 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.
