2020 Mercedes-Benz GLC 300 AMG Line DE 4MATIC A 1.9L Electric diesel · RO70 HWF

The vehicle remains roadworthy, but the maintenance trend shows a shift toward reactive rather than proactive care. The most recent test in October 2025 at 105,705 miles identified multiple minor advisories related to braking components and consumables. While the car passed, the presence of worn and deeply scored brake discs alongside defective wiper blades indicates that the previous owner is only addressing mechanical issues once they approach failure thresholds or are flagged during annual intervals. The GLC has covered significant mileage for its age, totaling over 105,000 miles in six years. This averages to approximately 17,600 miles per year, which is well above the national average for diesel diesel. A notable spike in usage occurred between August 2023 at 61,250 miles and July 2024, where the vehicle covered nearly 35,000 miles in just fourteen months. This high-intensity usage pattern accelerates the wear on the 4MATIC drivetrain, suspension bushings, and braking system. A buyer must prioritise a thorough inspection of the braking system and suspension geometry. The October 2025 record flagged deep scoring on the nearside rear inner brake disc and wear across all discs, suggesting the hardware is nearing replacement. Furthermore, recurring issues with uneven tyre wear—noted in July 2024 and October 2025—points to potential alignment issues or worn suspension components that have not been addressed. You should check for signs of excessive play in the control arms and ensure the high-mileage usage has not compromised the structural integrity of the undercarriage.
