2015 Mercedes-Benz C 2.1L Diesel · LN15 OHS

The 2015 Mercedes-Benz C-Class presents a stable and reassuring maintenance trend. The most recent MOT, conducted on 6 February 2026 at 90,563 miles, passed with zero defects recorded. This clean sheet extends back through every annual test in the provided history, including checks on 19 February 2025 at 86,324 miles, 7 February 2024 at 79,419 miles, 16 February 2023 at 73,996 miles, and 10 February 2022 at 70,114 miles. A five-year unbroken run of first-time passes with no advisories or failures indicates a vehicle that has been consistently well-maintained and kept in sound mechanical order. The mileage accumulation is steady and typical for an eleven-year-old vehicle. Between February 2022 and February 2026, the odometer advanced 20,449 miles across four intervals, averaging roughly 5,112 miles per year. The annual increments are consistent: 3,882 miles between 2022 and 2023, 5,423 miles between 2023 and 2024, 6,905 miles between 2024 and 2025, and 4,239 miles between 2025 and 2026. There are no suspicious gaps or sudden spikes that would suggest long periods of disuse or odometer irregularities. The current total of 90,563 miles aligns with approximately 8,233 miles per year over the vehicle's life, which is within normal parameters for a car of this age. Despite the clean MOT record, a buyer should still conduct a thorough in-person inspection focused on components not always fully assessed during a standard MOT. At this mileage, suspension bushes, coil springs, and shock absorbers may show age-related deterioration even if they have not yet reached a failure threshold. Brake discs, pads, and calipers deserve close attention, particularly the rear calipers, which can bind intermittently without triggering a test failure. The exhaust system and its mountings should be checked for corrosion, especially around joints and flexi-pipes. Tyre condition and alignment should be verified, as uneven wear can indicate underlying suspension geometry issues that a static MOT inspection might not capture. Structural integrity around the subframes, sills, and inner wing arches warrants a careful visual check for corrosion, as Mercedes-Benz models of this era can be susceptible to surface and, in worse cases, structural rust if not kept in dry conditions. The engine and transmission should be assessed for fluid leaks, smooth operation, and any signs of neglected oil or coolant service intervals. A clean MOT history is a strong positive indicator, but it does not substitute for a hands-on mechanical inspection by a qualified technician before purchase.
