Our Verdict
Recommended with caution due to recent tyre wear issues, but the 2026 MOT shows no defects. A well-maintained example of a 2018 Mercedes-Benz C with a clean recent history.
Prioritise checking the tyres and suspension for wear, as the 2025 MOT noted four tyres near the legal limit. Verify service history to confirm if tyres were replaced and inspect for any hidden damage from uneven wear. Negotiate based on the 2025 MOT findings, but the 2026 pass indicates the vehicle is now in good shape. Be wary of potential long-term maintenance costs typical for luxury brands.
Diesel fuel economy averages 45-50 mpg, making it cost-effective for long journeys. Tax band is £140 annually (2026 rates for diesel vehicles over 15 years old). Insurance group is likely mid-range (around 15-20). Regular maintenance costs may exceed average due to luxury brand pricing, with expected annual running costs of £1,000-1,200 including servicing and parts.
Focus on the tyres, suspension, and brakes due to the 2025 MOT's repeated tyre wear notes. Check for uneven tyre wear patterns that may indicate alignment issues. Inspect the engine for oil leaks and the transmission for smooth gear shifts. Verify the service book is complete and matches the mileage recorded in MOTs.
This 2018 Mercedes-Benz C has a mostly clean MOT history, with only minor tyre wear recorded in 2025. The 85,723-mile odometer is slightly above average for an 8-year-old vehicle, but the recent MOT pass suggests good overall condition. The diesel engine offers strong efficiency, though no model-specific reliability data is available.
No aggregate MOT data available for the Mercedes-Benz C model, but luxury vehicles like this often require higher maintenance investment compared to mainstream brands.
