2018 Mercedes-Benz C 2.1L Diesel · BA63 TYY

This 2018 Mercedes-Benz C-Class presents an exceptionally clean roadworthiness profile across five consecutive DVSA examinations, with the most recent assessment on 12 December 2025 recording a pass and zero defects or advisories. The trajectory is uniformly stable, showing no deterioration across the four prior tests dating back to April 2022, with each annual examination likewise returning a clean pass. The absence of any flagged advisories on suspension, braking, exhaust, or corrosion components over this period is notable for a vehicle of this age, suggesting that the structural and mechanical integrity has remained sound through its MOT history. While a clean record does not guarantee that all components are in as-new condition, it indicates that no items have deteriorated to the threshold requiring tester comment or failure. With 76,994 miles accumulated over approximately eight years, the vehicle averages around 9,600 miles annually, which sits squarely within the typical usage band for a UK-registered executive saloon. The mileage progression between tests is consistent and gradual, with no large jumps or extended periods of inactivity that might raise concerns about stale fluids, seized calipers, or deteriorated rubber components. There are no gaps in the testing record beyond the standard annual interval, confirming continuous road use. This steady accumulation rate means the consumables such as brake pads, discs, tyres, and the automatic transmission fluid will have been worked regularly, reducing the likelihood of corrosion-on-seize issues and providing reassurance that the drivetrain has not been left standing for prolonged periods. For a prospective buyer evaluating this car without any advisory history to guide specific concerns, the inspection priorities should shift toward the components most likely to require attention on a Mercedes-Benz C-Class approaching the 80,000-mile mark. On a test drive, listen carefully for any knocking or clonking from the front suspension over uneven surfaces, which would indicate worn lower control arm bushes or drop links, and pay particular attention to any vibration through the steering wheel under braking, a common symptom of warped front brake discs. The brake pedal should feel firm and progressive, with no sponginess that might suggest corroded brake lines or hydraulic issues. Steering response should be precise and free of excess play, and the vehicle should track straight without pulling to either side, which would otherwise point to worn suspension geometry or unevenly worn tyres. Further checks should include a thorough visual inspection of the underside for any oil residue around the engine sump, rocker cover gasket, and rear differential area, as well as for signs of coolant weeping from the radiator or expansion tank, which are common wear points on higher-mileage Mercedes-Benz vehicles. Examine the boot floor, wheel arches, and subframe mounting points for any surface corrosion, particularly around the rear arches where salt ingress can take hold. Inspect the exhaust system for signs of corrosion at the mounting rubbers and joints, and verify that the tyres are of matching brand and tread depth, as uneven wear across the axles can indicate alignment or suspension geometry issues. Finally, a diagnostic scan for any stored fault codes in the engine, transmission, and convenience control modules would be prudent, as MOT testing does not cover electronic systems, and any illuminated warning lights on the dashboard should be investigated before purchase.
