2020 Mercedes-Benz SLC 300 Final Edition Prem A 2.0L Petrol · C2 MOH

The 2020 Mercedes-Benz SLC 300 presents a stable and improving maintenance trend, culminating in a fully clean pass on 24 February 2026 at 25,865 miles with zero defects. This is a marked improvement over the January 2027 test, which flagged six separate advisories including worn front and rear brake discs and pads, slight play in both front wheel bearings, and slight distortion on both front road wheels. The fact that these items were addressed before the February retest suggests the previous owner responded promptly to the advisories, indicating attentive rather than neglectful ownership. The 2025 test also recorded inner front tyre wear close to the legal limit and a cut in the offside front tyre, while 2024 repeated the inner front tyre wear pattern and added sidewall cracking. These recurring tyre defects point to a consistent issue, likely related to alignment or suspension geometry, rather than simple neglect. The mileage profile is notably low for a six-year-old vehicle. At 25,865 miles, the annual average is approximately 4,311 miles per year, which is well below the UK typical annual mileage of around 7,000 to 8,000 miles. The record shows a gap of roughly 6,139 miles between March 2023 at 15,272 miles and March 2024 at 21,411 miles, representing about 14 months of moderate use. The subsequent intervals show more regular accumulation, with 2,234 miles covered between March 2024 and February 2025, and 2,244 miles between February 2025 and January 2026. The final 10 miles between the January and February 2026 tests confirm the January test was a pre-retest check. This pattern suggests the car has seen consistent but light use in recent years, which is generally favourable for mechanical preservation but warrants attention to components that deteriorate with age and inactivity rather than mileage alone. A buyer should inspect the front suspension and steering components carefully during any pre-purchase examination. The repeated advisories for inner front tyre wear across both the 2024 and 2025 tests, combined with the 2025 advisories for wheel bearing play and wheel distortion, suggest the front end may have underlying alignment or geometry issues. Request evidence of any suspension work, particularly to lower arms, track rod ends, and wheel bearings. The brake advisories in January 2026 were resolved, but a physical inspection of disc thickness and pad condition remains prudent to confirm the quality of the repair. Given the low mileage and recent clean pass, the powertrain and structural integrity appear sound, but a thorough underbody inspection for corrosion is advisable on any vehicle that may have spent extended periods stationary.
