2003 Mercedes CL 500 5.0L Petrol · LY02 SAL

The 2003 Mercedes CL 500 presents a broadly stable maintenance trend through its recent MOT history, with the most recent test conducted on 18 October 2025 at 127,241 miles resulting in a pass. The sole advisory recorded at that test was front brake pads wearing thin, a routine consumable item consistent with a vehicle of this age and mileage. The preceding tests in October 2024 and October 2023 both passed cleanly, indicating no persistent mechanical or structural defects have emerged over the last three years. The maintenance trend is therefore stable, with only minor wear items flagged. The mileage pattern tells an interesting story. Between October 2022 at 122,758 miles and October 2025 at 127,241 miles, the vehicle covered just 4,483 miles over three years, averaging roughly 1,500 miles annually. This is exceptionally low even for a 23-year-old grand tourer and suggests extended periods of limited use or storage. The record shows no anomalous gaps or sudden accumulation between tests, with mileage progressing steadily at around 1,100 to 1,200 miles per year between 2022 and 2024 before tapering further. Such light use can preserve mechanical components but also raises questions about seal deterioration, fluid condition, and tyre age from prolonged standing. A prospective buyer should pay close attention to the front braking system given the advisory on pad wear at the most recent test. Inspect the brake discs for lipping and uneven wear, and check whether the pads have been replaced since October 2025 or remain at their flagged thickness. The October 2023 failure for an offside rear fractured road wheel is noteworthy. While rectified for the subsequent test, a buyer should examine that wheel carefully for any signs of poor repair, cracking, or secondary damage to the tyre sidewall and suspension mounting points in that area. Tyre condition across all four corners warrants close scrutiny given the likelihood of aged rubber from low annual mileage rather than wear alone. Beyond the flagged items, the underbody and suspension deserve a thorough inspection. A vehicle covering fewer than 1,500 miles per year may have spent considerable time stationary, which can accelerate corrosion on brake lines, exhaust components, and subframe mounting points. Check the suspension bushes, coil springs, and dampers for deterioration that may not present as a MOT failure but could affect ride quality and handling. The nearside side repeater defect from October 2023 was minor and resolved, but a full electrical function test of all lights, indicators, and dashboard warnings remains prudent before purchase.
