2012 Mercedes SLS 6.2L Petrol · 3 EDN

The most recent MOT test for the 2012 Mercedes-Benz SLS, conducted on 2026-06-02, resulted in a clean pass with no recorded defects, marking a positive continuation of the vehicle’s roadworthiness. Over the past four years, the MOT history demonstrates a stable maintenance trend, with no failures or recurring issues beyond the single advisory noted in 2024. This consistency suggests that the vehicle has been subject to regular inspections and that any wear or potential issues have either been addressed or are currently within acceptable limits. The absence of multiple advisories or failures in the same category over the years further supports the reliability of this model within its mileage bracket, though the low mileage and extended periods of inactivity may have introduced subtle but notable wear patterns that warrant closer attention. The recorded mileage of 15,493 miles for a vehicle aged 14 years represents an exceptionally low annual usage rate of approximately 1,107 miles per year, which is far below the typical wear thresholds for this class of car. Such low mileage often correlates with prolonged periods of stationary use, particularly in climates prone to standing corrosion or fluid degradation. The extended intervals between MOT tests—spanning up to two years—could indicate either infrequent operation or deliberate deferral of maintenance, both of which may have contributed to the observed advisory on the near-side rear tyre in 2024. While low mileage generally reduces mechanical stress on components like brakes, suspension, and drivetrain, it also raises concerns about potential issues arising from prolonged exposure to environmental factors, such as corrosion to brake discs or calipers, fluid degradation in hydraulic systems, or tyre perishing from static ageing. Given the clean MOT history and the low mileage profile, the buyer should prioritise a thorough physical inspection to address both wear-related and age-induced risks. First and foremost, examine the tyres for signs of sidewall cracking or perishing, which can occur even at low mileage when the vehicle has been stationary for extended periods. Check the tread depth on all tyres, particularly the near-side rear tyre mentioned in the 2024 advisory, for any irregular wear patterns or edge wear that may indicate misalignment or suspension issues. During a test drive, listen for unusual noises from the rear suspension, such as clunking or rattling, which could signal worn suspension bushes or coil springs, and inspect the rear wheels for uneven tyre wear or binding calipers that might suggest brake system problems. Beyond tyres, assess the brake system for signs of corrosion or binding, especially on the near-side rear components, as prolonged standing can accelerate rust formation on discs and pads. Verify the condition of the 12V battery, which may have degraded further due to infrequent use, and check for any fluid leaks under the vehicle, including coolant, brake fluid, and power steering fluid, all of which can degrade over time when not actively circulated. Additionally, since the vehicle has not undergone a full service in several years, consider scheduling a comprehensive maintenance check to address time-based fluid servicing, such as the engine oil and filter, transmission fluid, and brake fluid, which should be renewed according to the manufacturer’s recommendations—typically every 60,000 to 100,000 miles or every two to three years, whichever comes first. Finally, inspect the exhaust system for emissions-related issues, such as catalytic converter blockages or excessive backpressure, which can become more problematic with age and low usage. A professional inspection or drive-by test for emissions compliance would be advisable to ensure compliance with current UK regulations.
