Mercedes Benz Cl (2014)
2014 Mercedes Benz Cl
CarHunch analysed 103 real MOT records for the 2014 Mercedes Benz Cl. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2014 Mercedes-Benz CL passes its MOT at 86.7%, which is solidly above the UK average of 80%, but nearly 39% of these cars have recorded a dangerous defect at some point—a significant concern for buyers, suggesting electrical or brake system issues are common. When failures do occur, they average 1.48 per vehicle, though the real eye-raiser is the 10.6 advisories per car, indicating these are high-mileage luxury cars that accumulate warning signs.
At a median of 50,141 miles for a decade-old car, these CLs are relatively well-used but not excessively so, making the high advisory count more telling—it's not just wear, it's the complexity of the platform catching up. Before buying one, obtain a full service history and have a Mercedes specialist inspect the electrical systems and suspension, as that advisory load suggests both are areas where costs will mount quickly.
What to check before buying a 2014 Mercedes Benz Cl
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.
- ⚠️ 38.8% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
