2021 Mercedes-Benz C 1.5L Hybrid electric · WM70 XVT

The most recent MOT test conducted on 5 February 2026 resulted in a pass, although a minor defect was recorded regarding the front windscreen wiper blade along with two advisories relating to the front brake discs and pads. Reviewing the sequence of tests over recent years, the maintenance trajectory shows a mild downward trend. The 2023 and 2024 tests were returned with no advisories or defects, whereas the 2025 test recorded all four tyres as being worn close to the legal limit or worn on edge, and the 2026 test then introduced the front brake component wear and the wiper blade issue. Although none of these items have yet resulted in a failure, the increasing frequency of advisories suggests that the vehicle is entering a phase where its consumable components are requiring closer attention. The recorded mileage of 36,108 miles over a five-year period equates to an average annual usage of roughly 7,222 miles, which is broadly consistent with typical private or mixed-use driving patterns. There are no obvious gaps in the recorded mileage progression across the MOT entries, suggesting the vehicle has been in consistent use rather than left standing for extended intervals. This steady rate of accumulation is generally favourable for mechanical longevity, as it reduces the risks associated with prolonged inactivity such as brake caliper seizure, oil seal drying, and undertray corrosion, while still being sufficient to keep all drivetrain and suspension components regularly loaded and exercised. Given the recurring advisories concerning tyre wear on all four corners in 2025, a prospective buyer should carefully inspect the current tyres for both tread depth and, more importantly given the vehicle's age, sidewall condition. Five-year-old tyres, even with adequate remaining tread, are susceptible to perishing and cracking from UV exposure and age-related rubber degradation, and Mercedes-Benz along with most tyre manufacturers recommend replacement regardless of tread once the tyres exceed five to six years of age. Verify the manufacturing date on the sidewall and inspect closely for any hairline cracks or bulging. Additionally, the front brake disc and pad advisories from the latest test indicate that these items are approaching the end of their service life; on a test drive, listen for any squealing, grinding, or scraping from the front wheels under light braking, and feel for any vibration, shudder, or pulling to one side through the steering wheel which may indicate disc runout or uneven pad wear. Beyond the recorded defects, there are several age-related checks that should be carried out on a five-year-old Mercedes-Benz C-Class. Inspect the brake calipers and discs for any surface corrosion or signs of binding, particularly if the vehicle has been stood for any period recently, and check the condition of the brake fluid, which typically requires replacement every two years regardless of mileage due to its hygroscopic nature. Examine the auxiliary 12V battery condition, including terminals for corrosion, as battery failure is common at this age. The coil springs, suspension bushes, and anti-roll bar links should be inspected for any cracking or deterioration, and the exhaust system checked for corrosion at mounting points and joints. Finally, confirm the vehicle's full service history including stamped book entries or digital records, and verify that all time-based servicing such as brake fluid, coolant, and transmission fluid has been carried out at the appropriate intervals.
