2014 Mercedes-Benz SL 3.5L Petrol · 72 MAG

The current roadworthiness of this Mercedes-Benz SL is marginal, as the most recent February 2026 test highlights a pattern of deferred maintenance that has resulted in a failure and subsequent pass with significant advisories. While the vehicle passed its latest inspection, the presence of recurring brake and tyre defects indicates that the owner has consistently opted for minimal compliance rather than proactive mechanical remediation. The trend is worsening, as evidenced by the escalation of brake disc wear into a severe axle imbalance that forced a test failure just days before the final pass. The vehicle has covered 48,724 miles over twelve years, averaging approximately 4,000 miles annually. This low usage is consistent across the recorded history, with steady increments of roughly 1,500 to 2,700 miles between annual tests. Such infrequent use often leads to the specific issues noted in the record, particularly the corrosion and pitting of brake components caused by long periods of inactivity. The mechanical health of the car is heavily influenced by this lack of regular exercise, which has clearly contributed to the degradation of rubber and metal parts. A prospective buyer must prioritise a thorough physical inspection of the braking system and suspension components. The persistent flagging of pitted, worn, and scored brake discs across all four corners suggests that the rotors are likely at or near their minimum thickness, necessitating a full replacement of discs and pads. You should also verify the condition of the brake pipes, as the recent advisory regarding corrosion covered in grease is a red flag that often masks deeper structural decay. The slight play in the nearside front lower suspension ball joint requires immediate attention to prevent accelerated tyre wear and compromised steering precision. Finally, the recurring tyre damage noted since 2025 confirms that the rubber is perishing, likely due to age rather than high mileage. Replacing these tyres is essential for safe operation. Given the history of underbody shields obscuring components, ensure that a technician removes these covers during a pre-purchase inspection to check for hidden corrosion on the chassis and subframes. This vehicle requires a significant budget for immediate remedial work to bring its mechanical state back to a reliable standard.
