2012 Mercedes-Benz C 2.1L Diesel · WN12 CUY

The 2012 Mercedes-Benz C-Class currently holds a valid MOT, having passed its most recent test on 12 March 2025 with no defects or advisories recorded by the DVSA examiner. This represents a positive maintenance signal, particularly when viewed alongside the preceding test on 13 March 2024, which also resulted in a clean pass. The only anomaly in the recorded history is a failure dated 5 December 2022, but the absence of any defect data for that test makes it difficult to confirm the exact nature of the issue; however, the immediate re-test just ten days later on 15 December 2022 was passed without recorded defects, suggesting the matter was resolved promptly and without lasting impact. Overall, the trajectory is stable and consistent with a vehicle that has been maintained to a satisfactory standard over recent years, with no escalating pattern of advisories or recurring problem areas. With a recorded mileage of 97,460 miles across approximately 14 years of service, this C-Class is accumulating mileage at a rate of roughly 6,961 miles annually, which is broadly typical for a vehicle of this age and class. The MOT history does not display any significant gaps in testing, and the relatively even pattern suggests the car has been in regular use rather than left standing for prolonged periods. That said, mileage of this level does imply that wear-affected components such as suspension bushes, coil springs, brake discs, and general drivetrain consumables will have experienced considerable real-world stress. A pre-purchase inspection should therefore account for the fact that, while the car has clearly been serviced regularly, mechanical items may now be approaching the latter portion of their service life. Given the clean MOT record, a prospective buyer should focus their evaluation on age and calendar-related deterioration rather than chasing specific flagged defects. First and foremost, the tyres warrant close physical inspection for sidewall perishing and cracking, which is common on vehicles of this vintage and is not always captured in an MOT if the tread depth remains within legal limits. Look for uneven shoulder wear, which could indicate tracking, suspension bushes, or shock absorber wear that may not yet have triggered an advisory. The 12V battery is also a likely candidate for imminent replacement given the car's age, particularly if it struggles to crank promptly on a cold morning, and it would be prudent to verify the battery's age and test its state of charge. Brake discs should be examined for visible corrosion, lipping, and any signs of a binding caliper, especially given the car has covered substantial mileage and may have experienced periods of lighter use. In addition to the above, a thorough inspection should include a check of all fluid conditions and service intervals. Brake fluid absorbs moisture over time and should be replaced regardless of mileage; if the history cannot confirm a recent change, this is a sensible preventative measure. Coolant, transmission fluid, and engine oil condition are equally relevant, and verifying service book stamps or digital records will help confirm whether the manufacturer-recommended schedule has been followed. During a test drive, listen for suspension clonks over uneven surfaces, particularly from the front struts and anti-roll bar bushes, and feel for any pulling under braking, which could suggest seized caliper slides or a warped disc. Finally, check for oil leaks from the engine sump, valve cover gasket, and rear differential area, as these are common on higher-mileage Mercedes vehicles and can prove costly if neglected. With the MOT record providing confidence in its current roadworthy condition, a diligent physical inspection and service history review should give a clear picture of the car's overall health.
