2018 Mercedes-Benz E 3.0L Petrol · ST03 NEY

A remarkably clean and consistent roadworthiness record defines this 2018 Mercedes-Benz E-Class, with four of its five recorded tests resulting in passes and no advisories of any kind. The single failure on 2023-08-22 is notable only for its unusual presentation, as it occurred without any specific defects being recorded against the vehicle. Because DVSA failure entries without listed defect codes are typically administrative or relate to components that were rectified at the time of test, this isolated entry does not establish any pattern of mechanical deterioration. With the most recent test on 2025-08-13 returning a clean pass and the two prior annual tests also recording no defects, the trend is one of stable and reassuring roadworthiness heading into late 2025 and beyond. The vehicle has covered 41,124 miles across approximately eight years of service, equating to an annual mileage of around 5,140 miles, which sits well below the typical usage rate for a premium executive saloon. There are no extended gaps in the MOT testing history, with tests consistently logged in August of each year, suggesting the car has been kept on the road continuously and is unlikely to have suffered the long stationary periods that often bring battery degradation, brake seizure, and dried-out rubber components. While the low annual mileage reduces wear on major drivetrain and clutch components, it does shift mechanical attention toward items that deteriorate with age rather than use, particularly brake discs, tyres, suspension bushes, and rubber boots, which can harden, perish, or develop surface corrosion even on a sparingly driven car. Given the absence of any recorded advisories, there is no specific component history to target during inspection, so a prospective buyer should focus on the general wear items most likely to require attention on an E-Class approaching eight years of age. On a test drive, listen for any clonks or knocks from the front suspension over speed humps or broken road surfaces, which would suggest worn control arm bushes or anti-roll bar drop links, both known to be sensitive areas on this generation of Mercedes. The steering should feel precise and self-centring without vibration through the wheel, and any pulling to one side under steady braking should be investigated as it may indicate a binding caliper or uneven pad transfer to the discs. Brake pedal feel should be firm and consistent, with no sponginess, and the discs themselves should be inspected for an obvious lip on the outer edge, as low-mileage cars frequently suffer from corroded or lipped discs that can produce judder under heavy braking. A thorough under-bonnet and under-vehicle inspection is still worthwhile, paying particular attention to the underside of the engine and the front subframe for any signs of oil misting or weeping, as oil leaks from the rocker cover and front crank seal are common on Mercedes petrol and diesel engines at this age. The underside should also be checked for any bubbling or surface corrosion along the suspension subframes, brake pipes, and exhaust hangers, as corrosion in these areas is a typical MOT advisory for vehicles of this vintage. Finally, given the low mileage, it is worth confirming that the timing belt or chain service interval, along with the most recent brake fluid and coolant changes, has been carried out in line with the manufacturer's time-based schedule rather than purely by mileage, as age-related fluid degradation is a common oversight on low-use executive cars.
