2021 Mercedes-Benz GLC 300 AMG Line Prem D 4M A 1.9L Diesel · MB21 CCU

The Mercedes-Benz GLC 300 presents as roadworthy with a stable maintenance trend. The most recent test on 18 March 2026 at 25,693 miles returned a pass with no defects recorded, continuing an unbroken clean history across three consecutive annual examinations. Mileage accumulation sits well below typical expectations for a five-year-old vehicle. The record shows 19,823 miles at the 13 March 2024 test, rising to 22,634 miles by 19 March 2025 and 25,693 miles by March 2026. That equates to roughly 3,000 miles per year, confirming light use with no abrupt jumps or standing gaps across the documented period. The DVSA data itself is sparse on advisories, which limits scope for deeper fault analysis. A buyer should still commission an independent inspection of suspension bushes, brake discs and calipers given the low annual mileage may mask seized components from prolonged inactivity. Drivetrain seals and tyre sidewall condition warrant physical checks, as rubber degradation correlates with age rather than miles covered. No structural corrosion, exhaust emission failures or recurring mechanical faults appear in the official history. The clean record implies conscientious prior ownership, though the absence of advisories across all three tests suggests the vehicle was barely stressed mechanically during its early life.
