2005 Mercedes CLS 3.0L Diesel · YR55 LMF

The 2005 Mercedes CLS presents a mixed maintenance picture. The most recent MOT, conducted on 20 April 2022 at 60,224 miles, passed but flagged both front tyres worn close to the legal limit. This is a minor consumable issue, yet it sits alongside a longer-term pattern of corrosion advisories that warrants caution. The overall trend is neither clearly improving nor sharply deteriorating, but rather one of deferred attention to corrosion-related items while basic consumables like tyres have been replaced intermittently. The mileage profile is notably low for a 21-year-old vehicle. Recorded at 60,224 miles today, the car has covered roughly 2,868 miles per year on average. Between the April 2018 test at 54,317 miles and the April 2022 test at 60,224 miles, just 5,907 miles were added over four years, averaging under 1,500 miles annually. The 2021 and 2022 tests show the mileage plateaued almost entirely, with only 2,785 miles added between April 2021 and April 2022, and no subsequent test recorded since. This suggests prolonged periods of inactivity, which can accelerate rubber perishing, brake seizure, and fluid degradation despite the low odometer reading. Corrosion is the recurring theme in this vehicle's history. The April 2021 test at 57,439 miles identified corroded brake pipes, a direct structural concern affecting braking integrity. The April 2019 test at 56,187 miles flagged corroding front and rear brake discs, indicating the braking system has been exposed to moisture and standing conditions. A prospective buyer should have the underside inspected thoroughly, paying close attention to brake pipe condition, subframe mounting points, and suspension components for rust jacking or perforation. Brake calipers should be checked for seized pistons, a common consequence of low-mileage, infrequently driven vehicles. Tyre wear has appeared repeatedly, flagged in both the 2019 and 2022 tests on the nearside and offside fronts. Uneven wear noted in 2020 suggests possible alignment issues or worn suspension bushes, particularly given the vehicle's age. The various undertrays fitted across multiple tests may have masked underlying corrosion or fluid leaks. A pre-purchase inspection should include a full four-wheel geometry check and a close examination of inner wing arches, sills, and exhaust mounting points for hidden corrosion that MOT undertrays can conceal.
