2004 Mercedes-Benz C 1.8L Petrol · LD54 MSV

A recurring theme in this car’s MOT record is the gradual deterioration of the rear brake hoses, first flagged as a slight deterioration on both sides in the 2023 test and still recorded as an advisory at the latest October 2025 pass, indicating that the brake line condition has not improved and may be approaching a point where replacement will be required. Apart from that, the history shows a single failure in 2020 linked to a nail in the rear tyre, while the remaining eight tests have been passes, with only occasional wear advisories on brake discs and registration plates, suggesting an overall stable roadworthiness trend but a specific emerging issue with the rear brake hoses. With 59,859 miles recorded over 22 years the vehicle averages roughly 2,700 miles per annum, well below typical usage for a car of this age. The low annual mileage points to light use or periods of storage, which reduces mechanical wear on consumables such as brakes, tyres and suspension components, yet it also means age‑related degradation of rubber and polymer parts can be a dominant factor. The MOT schedule shows regular annual testing from 2018 onward, with no long gaps, so the mileage figure is likely reliable and the vehicle has been subjected to consistent statutory checks throughout its life. Prospective buyers should give the rear brake system close attention. On a test drive, feel for any softening or sponginess in the brake pedal, especially under moderate braking, and listen for a faint hissing that could indicate a hose leak. A visual inspection should look for cracks, swelling or surface wear on the hose sections near the rear wheels, and the brake fluid reservoir should be examined for any signs of contamination. Because the front and rear brake discs were previously noted as worn or pitted, measuring disc thickness and checking for uneven pad wear will confirm whether the discs remain within safe limits or need resurfacing or replacement. Although the registration plate advisories are minor, a quick visual check to ensure legibility is prudent. Given the vehicle’s age, also inspect suspension bushings, ball joints and anti‑roll bar links for any looseness, creaking or excessive play when the car is driven over bumps. Look under the chassis for any signs of corrosion, particularly around the subframe and mounting points, as prolonged low‑usage can allow rust to develop unnoticed. A comprehensive pre‑purchase inspection that verifies the integrity of the rear brake hoses, overall brake wear, tyre condition and age‑related suspension components will provide a realistic picture of any imminent remedial work.
