Our Verdict
This 2018 Mercedes-Benz C presents mixed value. While the recent MOT pass suggests current roadworthiness, recurring tyre and brake issues raise concerns. Buyers should negotiate based on the 2025 failure and verify repairs.
Prioritise checking the nearside front wheel and tyre for structural damage, as these failed in 2025. Verify service records for brake pad replacements and tyre inspections. Negotiate a discount for the 2025 failure, and request a pre-purchase inspection to confirm repairs. Be wary of potential hidden costs from premium Mercedes parts.
A 1.5L petrol engine offers moderate fuel economy (approx. 35-40 mpg). Tax for 2023-2026 is £155 annually. Insurance groups for Mercedes C models typically range £100-150/month. Maintenance costs may exceed average due to the 2025 brake and tyre issues. Estimated annual running cost: £1,500-£2,000.
Inspect the nearside front wheel for cracks or distortion, and check the tyre for bulges or uneven wear. Test brake performance and confirm pad thickness. Examine suspension components for wear. Review service history for brake and tyre maintenance. Check for fluid leaks or unusual noises during a test drive.
The vehicle has a mostly clean MOT history with a recent failure in September 2025. Key issues included a distorted wheel, thin brake pads, and a tyre bulge. At 39,058 miles (10,000 annual average), mileage is typical for a 2018 model. No aggregate reliability data exists for this specific C model.
No aggregate MOT data available for the Mercedes-Benz C model. However, this vehicle's history shows specific mechanical vulnerabilities in brakes and tyres.
