2017 Mercedes-Benz C 2.1L Diesel · LL67 ADX

The 2017 Mercedes-Benz C has maintained a clean MOT history with no defects recorded across all tests, including the most recent inspection on 2023-02-21 at 26,467 miles. The absence of advisories or failures suggests the vehicle has been subjected to consistent, if not rigorous, maintenance over its service life. However, the duplicate entry for October 2021—where both a pass and a fail appear at the same mileage—indicates a potential administrative error rather than a mechanical issue. The last MOT test occurred nearly three years ago, placing the vehicle outside the current 12-month validity window. This is a critical oversight, as even a well-maintained car must undergo annual roadworthiness checks to confirm ongoing compliance with UK regulations. The recorded mileage of 26,467 miles over approximately nine years—roughly 2,941 miles annually—is unusually low for a vehicle of this age. The gap between the 2021 and 2022 tests spans 15 months, during which only 1,130 miles were accumulated, suggesting prolonged periods of inactivity. Such low mileage could imply the car has been stored for extended periods, potentially exposing components like suspension bushes, coil springs, and brake calipers to premature degradation from lack of use. The lack of advisories or failures does not negate the need for a thorough inspection of fluid levels, tyre condition, and structural integrity after such a long period off the road. Given the clean MOT record, the primary focus for an in-person inspection should centre on the vehicle’s long-term storage condition. Check for signs of corrosion on underbody components, particularly around wheel arches and suspension mounts, as low mileage does not exempt a car from environmental wear. The brakes, despite no recorded failures, should be assessed for uneven wear or binding calipers, especially if the vehicle has been stationary for extended periods. Tyres, though not flagged in MOTs, may require inspection for cracking or uneven tread wear, as prolonged storage can accelerate degradation. Finally, verify the integrity of the exhaust system and catalytic converter, as emissions-related failures are often silent until they become severe. The absence of advisories does not guarantee these areas are flawless—only that they passed the most recent test.
