Expert automotive synthesis from historical MOT defect records and market benchmarks.
Our Verdict
Recommended for its clean MOT history and low mileage, but inspect tyres and service records for potential hidden issues.
Prioritise a thorough inspection of the tyres, as the 2026 MOT noted outer tyre wear close to the legal limit. Verify service history for regular maintenance, particularly for diesel-specific components like the particulate filter. Negotiate based on the vehicle's low mileage, but be cautious of potential hidden costs associated with luxury diesel ownership. Check for any unrecorded repairs or accident history via the VIN.
Diesel fuel economy for the 2.9L engine is moderate, with combined figures around 35-40 mpg. Tax falls into a higher band due to diesel emissions, with £140 first-year rate and £470 annual after 2020. Insurance group 15-20 is typical for this model. Maintenance costs may exceed average due to complexity, with £500-700 annually for servicing and parts. Estimated annual running cost: £1,000-£1,200.
Focus on the tyres, checking for uneven wear or damage beyond the MOT report. Inspect the diesel particulate filter and exhaust system for clogging or leaks. Check for oil leaks, which are common in older Mercedes diesels. Review the service book for regular oil change intervals and any recorded issues. Test all electronic systems, as software glitches can occur in this model.
This 2018 Mercedes-Benz CLS has a mostly clean MOT history with only one minor tyre-related failure in its most recent test. At 56,038 miles, the mileage is below average for an 8-year-old vehicle, suggesting careful ownership. No aggregate reliability data is available, so individual history and condition checks are critical.
No aggregate MOT data available for the Mercedes-Benz CLS model, making individual vehicle history the primary indicator of reliability.
