2017 Mercedes-Benz C 220 AMG Line Premium D Auto 2.1L Diesel · AG57 LEX

This Mercedes-Benz C 220 AMG Line Premium D Auto presents a clean MOT history, with the most recent test in October 2025 at 85,252 miles showing no defects—an outcome consistent with the three preceding annual passes. The only anomaly is a failed test in August 2022 at 45,699 miles, though no specific faults were recorded, suggesting either a minor administrative oversight or a non-mechanical issue resolved before the retest. The absence of advisories or recurring defects over the past three years indicates stable maintenance, with no signs of worsening wear in critical areas like brakes, suspension, or structural integrity. That said, the brief failure in 2022 raises a minor red flag: without documented faults, it implies either a procedural error or a problem addressed promptly by the owner, which could reflect either meticulous upkeep or a one-off oversight. The mileage accumulation of 85,252 miles over nine years—roughly 9,472 miles annually—aligns closely with average usage for a vehicle of this age, suggesting neither excessive nor negligible driving. The gap between the 2022 failure (45,699 miles) and the next test (36,750 miles in September 2022) is unusual, as mileage appears to have decreased by 8,949 miles in just over a month. This inconsistency could indicate a clerical error in mileage recording or, less likely, a period of non-use or odometer tampering. Subsequent mileage increments remain steady, with 14,066 miles added between October 2022 and October 2023, and another 14,131 miles between October 2023 and October 2024, reinforcing a pattern of regular, moderate use. Given the absence of defects, a prospective buyer should prioritise a thorough inspection of components prone to long-term wear or hidden corrosion, particularly in a premium vehicle like this. The suspension—specifically front lower wishbone bushes, coil springs, and anti-roll bar links—should be checked for signs of fatigue or leakage, as these are common failure points in AMG models with higher ride stiffness. Brakes, including caliper slides, pistons, and brake fluid condition, warrant scrutiny, even though no advisories were logged; binding calipers or uneven disc wear could develop silently. Structural integrity, especially around wheel arches and underseal, should be examined for corrosion, particularly if the vehicle has been garaged in damp conditions. Finally, the exhaust system’s mounts and flexibility should be verified, as rust or fatigue in this area can lead to premature failure. While the MOT record is reassuring, these areas are critical for long-term reliability in a high-performance luxury saloon.
