2017 Mercedes-Benz SL 3.0L Petrol · AJ66 YFO

The 2017 Mercedes-Benz SL presents a stable roadworthiness trend. The most recent test on 14 May 2025 at 44,654 miles returned a pass with no defects recorded, following a clean pass on 22 May 2024 at 42,276 miles. The only blemish is a failed test on 16 May 2024 at 42,274 miles that recorded no defects, immediately superseded by the pass six days later. This suggests an administrative or presentation anomaly rather than a mechanical fault. Mileage accumulation is low for a nine-year-old vehicle. The record shows 36,104 miles at the 12 May 2022 test, rising to 39,263 by 25 April 2023, then 42,274 by 16 May 2024. The car covered just 2,380 miles between May 2024 and May 2025. Annual averages sit near 4,960 miles. Such low use implies light running but also raises the prospect of prolonged standing periods, which can degrade tyres, brake discs, and suspension bushes through inactivity. The clean MOT history gives no advisories on corrosion, suspension, brakes, or exhaust emissions across all five entries. A buyer should still commission an independent inspection of structural integrity and underbody condition given the age. Standing time can conceal flat-spotted tyres, seized calipers, or perished rubber components not captured in a pass result. The May 2024 fail with zero defects warrants a check of the original test station notes. If confirmed as a non-mechanical rejection, the vehicle's maintenance record reflects conscientious annual testing. No recurring faults or worsening patterns emerge from the data supplied.
