2017 Mercedes-Benz C 2.1L Diesel · MR55 PTZ

This 2017 Mercedes-Benz C-Class presents a fundamentally sound MOT record, with all tests since 2022 resulting in passes and no recorded structural or mechanical failures on subsequent examinations. The single failure on file occurred in September 2023 and was caused by a nearside rear tyre with tread depth below the legal 1.6mm threshold, classified as dangerous. The vehicle passed the very same inspection on re-test just five days later after presumably addressing the tyre, and the two subsequent annual tests in May 2024 and June 2025 both returned clean passes with no advisories whatsoever. This indicates a stable and reliable mechanical state, with the only flagged items being tyre-related wear and a single advisory regarding rear brake pad thickness, neither of which points to any underlying structural, corrosion, or systemic mechanical concern. With 96,638 miles accumulated over approximately nine years, this C-Class has covered roughly 10,738 miles per year, placing it squarely within typical usage parameters for its age cohort. There are no anomalous mileage jumps between tests or extended periods off the road, suggesting the vehicle has been in consistent, regular use rather than suffering long dormant spells that could promote corrosion, brake seizure, or fluid degradation. Mechanically, this steady mileage profile generally favours even wear across suspension components, drivetrain, and braking systems, though consumables such as tyres, brake pads and discs should still be expected to require periodic replacement at this odometer reading. The absence of any advisories concerning oil leaks, suspension play, or exhaust condition across the recent test history is a positive indicator given the mileage level. Given the recorded advisory on rear brake pad wear and the tyre edge wear observations from 2023, particular attention should be paid to the braking system during a pre-purchase inspection. On a test drive, listen for any grinding or squealing from the rear calipers, particularly on cold starts when binding calipers are most audible, and feel for any judder or pulsing through the brake pedal which could indicate disc warping. The current state of the rear pads and discs should be physically measured with a torch or thickness gauge, as the advisory suggests they were approaching the end of their service life over two years ago. Should the warning light illuminate on the dashboard for pads or brakes, this would confirm the system has not been maintained since that advisory. The front tyre inner-edge wear flagged in 2023 is worth investigating as it can be symptomatic of suspension geometry misalignment, particularly worn wishbone bushes, track rod ends, or top mount deterioration. During a road test, pay close attention to any pulling to one side under acceleration or braking, vague or wandering steering feel, or clonking noises from the front suspension over uneven surfaces and speed bumps. Excessive inner-edge wear persisting after a tyre change may also point to incorrect wheel alignment specifications, so requesting evidence of a recent four-wheel alignment would be prudent. Additionally, with a vehicle of this mileage, a thorough inspection of the underbody for corrosion on subframes, brake lines, and fuel lines is advisable, as the MOT history shows no corrosion advisories but the chassis is now entering the age range where surface corrosion can begin to manifest on ferrous components.
