2021 Mercedes-Benz C 1.6L Petrol · X800 ADE

The most recent MOT, carried out on 10 December 2025, was passed with no recorded failures and only a single advisory concerning the front tyres being close to the legal tread limit and showing edge wear. The two preceding tests in March 2025 and March 2024 were both clean passes, indicating a generally stable maintenance record with no progressive defects emerging over the past two years. The only recurring point of attention is the tyre wear advisory, which suggests that tyre condition should be re‑evaluated before purchase. With a recorded 43,941 miles on a 2021 Mercedes‑Benz C‑Class, the vehicle averages roughly 8,800 miles per annum. This mileage is typical for a five‑year‑old executive saloon and does not signal excessive use. There are no large gaps in the mileage progression that would imply prolonged periods of storage, nor is there a rapid accumulation that would accelerate wear on high‑stress components such as the suspension, brakes or drivetrain. Consequently, the wear on consumables should be in line with normal calendar‑based degradation rather than extreme mileage‑driven fatigue. The front tyre advisory warrants immediate visual inspection. Measure the tread depth on both front tyres; anything below 3 mm is approaching the legal minimum and may already be compromised in wet grip. Examine the sidewalls for cracking, bulging or dry‑rot, especially if the car has spent time standing still, as ageing rubber can deteriorate even with modest mileage. Check the rear tyres for matching wear patterns, as uneven front wear can indicate mis‑alignment, worn front suspension bushes or a binding front axle. During a test drive listen for a hollow or thumping noise when cornering, which would corroborate suspension or steering component wear, and feel for any vibration that could be transmitted from a deteriorating tyre or wheel bearing. Beyond the tyres, a five‑year‑old Mercedes‑Benz should be examined for age‑related items. Verify the condition of the 12 V battery; a load test or voltage check can reveal reduced capacity that may cause starting issues. Inspect the brake discs for surface rust, scoring or glazing, and ensure the pads have sufficient thickness, as standing periods can promote disc corrosion and uneven pad wear. Examine all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for proper level and signs of contamination; fluids typically require replacement on a calendar basis even if mileage is modest. Finally, confirm that the service book shows regular oil changes, filter replacements and any scheduled timing‑chain or belt services appropriate to the model, as adherence to the manufacturer’s service intervals is a strong indicator of overall mechanical reliability.
