2016 Mercedes-Benz SLC 2.0L Petrol · OV66 WHP

The latest MOT test on 2025-11-05 resulted in a pass, though it included a single advisory regarding a near-side rear tyre showing minor damage, which is a relatively straightforward issue likely related to a minor impact or road debris incident. Despite this, the overall maintenance trend over the past six years remains stable, with no repeated failures or persistent defects beyond the tyre advisories. The vehicle has consistently passed MOTs until 2019, when it failed due to a front tyre structural failure—a critical issue that would have rendered the vehicle unsafe if unaddressed—and then passed subsequent tests with only tyre-related advisories, indicating that the underlying structural integrity of the tyres has since been restored. This suggests that while the tyre wear and damage are the primary concerns, they have been managed appropriately, and the vehicle’s roadworthiness has been maintained through corrective action. The recorded mileage of 33,992 miles for a vehicle aged ten years represents a notably low annual usage rate of approximately 3,399 miles per year, which is unusually low for a car of this age and model. Such low mileage often correlates with periods of prolonged inactivity, where components like brakes, suspension, and fluids can degrade due to standing or seasonal storage. For example, standing brakes may develop corrosion on disc surfaces or binding calipers, leading to uneven wear or reduced braking efficiency. Similarly, suspension bushes and coil springs can stiffen or dry out over time, causing clunking noises during cornering or uneven ride height. The low mileage also raises concerns about calendar-based degradation of fluids, such as brake fluid, which can absorb moisture and become less effective over extended periods, or engine oil that may thicken or lose its lubricating properties. Additionally, tyres can suffer from sidewall cracking or perishing due to exposure to UV light and temperature fluctuations, even if the tread depth is legally compliant. Given the recent MOT advisory on the near-side rear tyre and the historical tyre wear issues, the prospective buyer should prioritise a thorough inspection of all four tyres. Check for any additional lumps, cuts, or signs of structural compromise beyond the noted front tyre failure, and verify that the tread depth is consistent and free from irregular wear patterns that could indicate misalignment or suspension issues. On a test drive, listen for unusual noises such as clunks from the rear suspension, which may signal worn suspension bushes or damaged coil springs, and monitor braking performance for any signs of shuddering or uneven stopping, which could indicate warped discs or contaminated brake fluid. The front tyre failure from 2019 underscores the importance of ensuring the vehicle has been serviced with fresh brake fluid and that all brake components—including calipers, brake pads, and hoses—are in good condition. For a vehicle of this age and low mileage, the buyer should also focus on practical checks that address potential standing-related wear and fluid degradation. Inspect the brake discs for signs of corrosion, rust, or binding, particularly near the rear where standing can exacerbate issues. Check the brake fluid level and condition, as well as the engine oil, transmission fluid, and differential fluid for any signs of contamination or degradation, and ensure all fluid reservoirs are topped up and sealed. Additionally, verify the condition of the 12V battery, as prolonged disuse can lead to sulphation or reduced capacity, and test the starter motor and alternator for proper function. Finally, examine the vehicle’s exterior for signs of rust, particularly around wheel arches, rocker panels, and undercarriage, as low mileage can sometimes mask the effects of prolonged exposure to moisture and road salt. Lastly, confirm that the vehicle’s service history is up to date, especially for items like suspension servicing, timing belt replacement, and fluid changes, which are critical for maintaining long-term reliability.
