2015 Mercedes-Benz CLS 2.1L Diesel · WG65 AAZ

The most recent MOT test on 2026-02-25 resulted in a clean pass, confirming the vehicle’s roadworthiness at that time. Over the past five years, the CLS has consistently achieved passing grades without any recorded failures, suggesting a generally stable maintenance record. However, the presence of advisories in the 2022 test—particularly regarding front bonnet retention, brake disc wear, and tyre cuts—indicates that while the vehicle remains functional, certain components are approaching or have already reached their operational limits. These advisories, particularly the front bonnet deterioration and rear brake disc scoring, warrant closer attention, as they may signal underlying wear patterns or potential long-term issues if not addressed promptly. The vehicle’s recorded mileage of 97,528 miles at the time of assessment reflects a moderate annual usage rate of approximately 8,866 miles per year, which is within the expected range for a 11-year-old car of this class. The consistent mileage accumulation suggests regular driving habits, though the absence of significant mileage gaps does not necessarily imply excessive wear—particularly if the vehicle has been used in mixed conditions (e.g., urban, highway, and off-road segments). However, the advisories on brake discs and tyres could be exacerbated by higher mileage or aggressive driving, which may accelerate wear on consumables like brake pads, suspension components, and tyre tread integrity. It is also worth noting that the nearside front and rear tyres show cuts that, while not severe enough to fail the MOT, could indicate underlying issues such as poor alignment, uneven load distribution, or damage from road debris. Given the clean MOT history since 2022 and the advisories present, the prospective buyer should conduct a thorough pre-purchase inspection to assess the severity and progression of the noted defects. The front bonnet retaining device’s deterioration could lead to structural integrity concerns if not replaced, potentially compromising the vehicle’s crashworthiness or causing leaks. During a test drive, listen for any unusual noises from the bonnet area, such as rattling or creaking, which may signal further loosening or failure of fasteners. The scored rear brake discs suggest that the pads may have worn thin or that the discs are experiencing uneven heat distribution, which could result in reduced braking performance or premature disc failure. Inspect the rear brake system for any signs of binding, excessive heat discolouration, or warping, and check for a consistent pedal feel without sponginess or excessive travel. For the tyres, the nearside front and rear cuts should be monitored closely, as they may worsen with continued use. On a test drive, observe for uneven tyre wear patterns, which could indicate misalignment, suspension issues, or incorrect load distribution. The cuts themselves may not cause immediate failure but could lead to blowouts or reduced traction if they deepen. Additionally, since the vehicle is approaching its 11-year mark, the buyer should verify the condition of the tyres for signs of sidewall cracking or perishing, which can compromise structural integrity and safety. Beyond the MOT advisories, a practical inspection should include checking the 12V battery for corrosion, swelling, or reduced charge capacity, as older vehicles are more prone to battery failure, especially if the car has been left standing for prolonged periods. The engine oil, transmission fluid, and coolant should also be inspected for signs of degradation or contamination, with a recommendation to replace fluids that have exceeded their service life, typically every 60,000 to 100,000 miles or every 5 to 10 years, depending on the manufacturer’s guidelines. Finally, verify the service history for any missing or outdated stamps, particularly for suspension components, brakes, and exhaust systems, as these areas are prone to wear at this mileage and age.
