2017 Mercedes-Benz GLC 2.1L Diesel · LL67 XST

The most recent MOT test conducted in September 2025 resulted in a pass, though it followed a failure due to a major defect involving a nearside rear tyre with a cut reaching the cords. The overall maintenance trend indicates a slight shift from a period of clean passes to the emergence of wear-related issues. While the vehicle has been consistently tested, the recent appearance of suspension advisories and tyre failures suggests that the vehicle is entering a phase where consumable components and suspension elements require more frequent monitoring and replacement. With 56,186 miles recorded over approximately nine years, the vehicle has averaged roughly 6,243 miles per year. This mileage profile is relatively low for a Mercedes-Benz GLC, suggesting it has not been subjected to heavy long-distance motorway use. While this typically means less mechanical wear on the engine, gearbox, and drivetrain, low-mileage vehicles can occasionally suffer from secondary issues such as fluid degradation or the hardening of rubber seals and bushes due to age and infrequent operation. A primary concern for a prospective buyer is the advisory regarding the offside front suspension arm ball joint exhibiting slight play. During your inspection and test drive, pay close attention to the steering feel and listen for any rhythmic knocking, clunking, or metallic clicking sounds when driving over speed bumps or uneven road surfaces. If the ball joint wear has progressed, it may cause instability or imprecise steering. Furthermore, given the recent failure for a tyre with structural damage, you must inspect the remaining tyres for any signs of impact damage, sidewall bulging, or uneven wear patterns that might suggest an alignment issue. Due to the vehicle's age and relatively low annual mileage, you should also conduct a thorough check of all rubber-based components. Inspect the tyre sidewalls for perishing or fine cracking, which can occur from age-related ozone degradation even if tread depth remains high. Check the brake discs for heavy corrosion or pitting and ensure the calipers are not binding, which can happen if the vehicle has been parked for long periods. Finally, confirm that time-sensitive maintenance, such as brake fluid replacement and engine coolant refreshes, has been documented in the service history, as these are critical for maintaining the structural and mechanical integrity of the vehicle.
