2014 Mercedes-Benz SL 3.0L Petrol · X2 DJF

The vehicle currently holds a valid MOT pass from November 2025 at 71,725 miles, confirming it meets minimum roadworthiness standards. However, the maintenance trend is deteriorating. The most recent advisory for a coolant leak represents a new and concerning fault, indicating potential overheating risks or internal component degradation. This follows a pattern of persistent rear brake wear and a recurring offside rear indicator failure, both of which have remained unresolved across multiple tests since 2022. The nearside front service brake also showed fluctuation in the latest test, suggesting brake hydraulic or mechanical inconsistency. Mileage accumulation is exceptionally low for a 12-year-old vehicle, averaging roughly 5,977 miles annually. This suggests either very light usage or prolonged periods of inactivity, which can lead to component seizing, fluid degradation, and accelerated wear when the vehicle is eventually driven. The gap between the November 2025 test and the current date is minimal, so the vehicle's condition is relatively recent. No evidence of rapid mileage spikes exists, but the low usage pattern raises concerns about potential moisture buildup in the fuel system, brake components, or tyres. Buyers should prioritise a thorough inspection of the cooling system, given the recent coolant leak advisory, as left unchecked this could result in costly engine damage. The rear brake assembly requires immediate attention, with pads and discs showing consistent wear that may indicate binding calipers or uneven loading. The persistent offside rear indicator fault suggests a wiring or bulb holder issue that should be diagnosed. Given the vehicle's age and low usage, a full suspension check is advisable, focusing on bushings, coil springs, and shock absorbers that may have corroded or seized. Finally, inspect all four tyres carefully, particularly the nearside rear, which previously suffered a structural bulge, and verify that no residual damage remains in the wheel assembly or suspension components.
