Our Verdict
Recommended for careful buyers, but investigate the 2023 MOT failure. Recent MOTs show strong reliability, but the 2023 failure raises questions.
Ask the seller to clarify the 2023 MOT failure—confirm whether it was a genuine failure or an administrative error. Check for a full service history, particularly for diesel-specific maintenance (e.g., DPF, EGR valve). Negotiate based on the mileage and the 2023 MOT anomaly. Be wary of potential hidden costs associated with luxury diesel maintenance.
Diesel fuel economy is moderate for a 2.9L engine, with typical costs around £1.30-£1.40 per litre. Tax band is £150 annually (2018 registration). Insurance group is likely mid-to-high, typical for a premium diesel. Maintenance costs may exceed average due to complexity, with DPF repairs or turbocharger issues possible. Estimated annual running cost: £1,200-£1,500.
Inspect the DPF (diesel particulate filter) for clogging, common in older diesels. Check for soot buildup in the engine bay and exhaust. Verify the EGR valve is clean. Review service records for oil changes and filter replacements. Examine the 2023 MOT report for any unrecorded defects. Test drive for unusual noises or emissions.
This 2018 Mercedes-Benz CLS has a clean MOT history from 2022 to 2025 with no defects, but a 2023 failure (despite 'no defects recorded') introduces uncertainty. At 64,601 miles, the mileage is slightly above average for an 8-year-old vehicle. The 2.9L diesel engine is reliable but requires careful inspection.
No aggregate MOT data available for the MERCEDES-BENZ CLS model, making it difficult to assess broader reliability trends.
