Our Verdict
Proceed with caution and a thorough mechanical inspection. While the most recent MOT record shows no defects, the vehicle's mileage is significantly higher than the model average.
Given that this 2.1L diesel engine has covered much more mileage than the typical example, your primary focus should be on the service history. You must verify that oil changes have been performed at the correct intervals to protect the turbocharger and engine components.
Negotiate based on the higher-than-average mileage. Ask for evidence of recent maintenance on items common to this model's aggregate data, such as tyres, headlamps, and suspension arms, as these are frequent failure points across the wider Mercedes-Benz C-Class fleet.
As a 2143cc diesel, this vehicle is likely to offer efficient motorway cruising but may face higher costs in stop-start urban environments. Tax bands for this era of C-Class vary depending on specific CO2 emissions, so check the exact VED rate before purchase.
Insurance groups for Mercedes-Benz models tend to be mid-to-high, and maintenance costs will reflect the premium nature of the brand. Expect typical running costs to be higher than a non-premium hatchback due to parts and specialist labour requirements.
Check the condition of the tyres and the alignment of the headlamps, as these are statistically the most common MOT failure reasons for this model. Pay close attention to the suspension components; listen for knocks or rattles when driving over uneven surfaces, as suspension arms are a known aggregate failure point.
Because the vehicle has covered over 80,000 miles, inspect the brake discs and pads for wear, and check for any signs of fluid leaks around the engine bay. Ensure the diesel particulate filter (DPF) is functioning correctly, as high-mileage diesels can sometimes face issues if not driven on long runs.
This 2018 Mercedes-Benz C-Class diesel, finished in black, has covered 81,673 miles as of its last recorded MOT in March 2022. This mileage is substantially higher than the aggregate model average of 7,583 miles per year for a vehicle of this age. Although the 2022 test resulted in a pass with no defects, the history shows a failed attempt on the same day at the same mileage.
Aggregate data for this model shows an 82.2% MOT pass rate, with common issues relating to tyres, lighting, and suspension.
