Our Verdict

A strong recommendation for buyers seeki

Given the very low annual mileage, it is essential to verify the service history to ensure oil changes were performed at regular intervals regardless of distance, as diesel engines can be prone to sludge when under-utilised. Check for any signs of brake disc corrosion or perished rubber components, which can occur on vehicles that spend long periods stationary.

Negotiate based on the age of the vehicle, but recognise that the low mileage adds significant value. Ensure that all electronic systems are functioning correctly, as low-use premium cars can occasionally develop dormant electrical faults.

The 2.1L diesel engine is designed for efficiency, particularly on longer journeys, though urban fuel economy will be lower. Tax and insurance will be aligned with its 2012 registration and diesel emissions bracket, which is typically higher than modern equivalents.

Maintenance costs for the C-Class are generally moderate, though parts for the premium Mercedes-Benz range can be more expensive than for mass-market brands. Annual costs including fuel, tax, insurance, and routine servicing are estimated to be mid-range for an executive car.

While this specific vehicle has no defects recorded in its recent MOT history, buyers should specifically inspect the suspension arms and tyres, as these are the most common failure points for this model across aggregate data. Check the headlamps for any clouding or failure, as this is another frequent issue for the C-Class.

Inspect the underbody for any signs of corrosion and check the condition of the silver paintwork for age-related fading or stone chips. A physical check of the tyre tread depth is advised, despite the low mileage, to ensure they have not perished due to age.

This silver 2012 Mercedes-Benz C-Class diesel has covered 49,861 miles as of July 2025, which is significantly below the average for its age. The MOT record shows consistent passes from 2022 to 2025, with only one failure recorded on the same day as its most recent pass. It presents as a rare, low-usage example of the 2148cc diesel variant.

The C-Class demonstrates a solid reliability profile with an average MOT pass rate of 82.2% across 419,691 analysed vehicles.
