2020 Mercedes-Benz GLC 300 AMG Line DE 4MATIC A 1.9L Electric diesel · GL11 JON

The vehicle presents a stable and improving mechanical picture at its most recent MOT test on 18 August 2025 at 33,579 miles, where it passed with only a minor advisory for slight corrosion on the inner edges of the front brake discs. A retest on the same day at 33,574 miles had failed due to an excessively worn offside front lower suspension arm ball joint, but this was clearly rectified before the pass. The suspension wear pattern is notable: the offside front ball joint was flagged with slight play in August 2024 at 24,324 miles and then deteriorated to an excessive wear failure by August 2025. This suggests the component degraded over roughly 9,255 miles in one year, yet the prompt repair indicates the owner addressed the fault rather than neglecting it. Tyre condition has been a recurring minor issue, with advisories for worn tread and exposed cords appearing in 2024, but no tyre defects were flagged in the 2025 test, implying better consumable management recently. The recorded mileage of 33,579 miles across six years averages approximately 5,596 miles annually, which is low for a vehicle of this age. The mileage progression is clean and consistent: 17,393 miles in September 2023, 24,324 miles in August 2024, and 33,579 miles in August 2025, representing roughly 6,931 miles over the most recent twelve-month period. This is a modest uptick from the earlier average but remains well within normal use. There are no suspicious gaps or sudden jumps in the odometer record, and the MOT tests align logically with the mileage accumulation, giving confidence that the history is genuine and not indicative of a rolled-back clock. A buyer should still inspect the front suspension carefully, particularly the offside lower suspension arm ball joint and its associated spring link, given the documented progression from slight play to excessive failure within a single year. The slight corrosion noted on the inner edges of the front brake discs in 2025 is a minor concern typical of low-mileage vehicles that may sit for extended periods, but it warrants a visual check to confirm the discs have not developed lipping or uneven wear patterns. The tyre history suggests uneven wear and edge wear were recurring issues in 2023 and 2024, so examining the current tyre sidewalls and tread depth across all four corners will reveal whether alignment and inflation have been properly managed. Finally, a brief road test focusing on front-end knocking over rough surfaces and straight-line braking stability will confirm the suspension repair is holding and that the corrosion on the discs has not progressed to a point affecting braking performance.
