2015 Mercedes-Benz SL 3.0L Petrol · PC 1674

The most recent MOT, carried out on 22 December 2025, was passed with no recorded defects, and the preceding eight‑year record shows a consistent pattern of passes with only a single advisory noted in 2022. This indicates a generally stable maintenance regime, with no evidence of deteriorating safety‑critical components over the period examined. The isolated tyre advisory does not suggest a systemic failure, but it does highlight that tyre wear has been monitored and addressed at least once in the recent past. With a recorded 30 230 miles on a 2015 model, the vehicle averages roughly 2 750 miles per annum, which is considerably below the typical UK usage of 7‑10 000 miles per year for a saloon of this class. Such low annual mileage often points to intermittent or limited use, possibly including extended periods of storage. While reduced wear on drivetrain and suspension elements can be advantageous, prolonged standing can accelerate rubber hardening, battery sulphation, and corrosion of brake discs and caliper pistons, all of which are time‑dependent rather than mileage‑dependent. Prospective buyers should give particular attention to the tyre set, confirming that all four tyres have been replaced since the 2022 advisory and that the current tread depth exceeds the legal minimum of 1.6 mm on both the inner and outer edges. Even with low mileage, tyre sidewalls can develop age‑related cracking or perishing, especially if the vehicle has been stored in a hot or UV‑exposed environment; visual inspection for dry rot, bulges, or uneven wear is essential. The suspension should be examined for any play in the front and rear bushes, as rubber components can become brittle with age, and the coil springs should be checked for corrosion or sagging. Brake discs, particularly on the rear axle, should be inspected for surface rust or pitting that could cause shudder, and the caliper pistons should be moved to verify they are not seized. During a test drive, listen for any clunking or knocking from the front suspension, especially when negotiating bumps, which could indicate worn bushings or loose mounting points. Observe the steering response for any looseness or vibration that might betray worn tie‑rod ends or a deteriorating steering rack. Apply the brakes firmly at varying speeds; any pulsation, judder, or noise may reveal warped discs or sticking calipers. Finally, check the 12 V battery voltage and assess whether the electrolyte level is adequate if it is a conventional lead‑acid type, as prolonged inactivity can reduce cranking performance. Verifying that the service book contains regular oil, filter, and coolant changes will further corroborate that the vehicle has been maintained in line with Mercedes‑Benz recommendations despite its low mileage.
