2020 Mercedes-Benz GLC 300 AMG Line Prem + D 4M A 1.9L Diesel · J24 NJD

The Mercedes-Benz GLC 300 presents as roadworthy with a stable maintenance trend. The most recent test on 12 January 2026 at 56,281 miles returned a pass with no defects recorded, and the preceding three annual tests also passed cleanly. The single failure entry dated 7 October 2023 at 27,451 miles carries no recorded defects, indicating an administrative or data anomaly rather than a mechanical fault. Across the visible history the vehicle shows no recurring advisories or worsening condition. Annual mileage sits at roughly 9,380 miles, typical for a six-year-old vehicle of this class. The records show 27,451 miles at the October 2023 test, rising to 42,705 miles by October 2024 and 46,192 miles by February 2025, then 56,281 miles at January 2026. The jump between October 2023 and October 2024 reflects about 15,250 miles in twelve months, above the average but not extreme. The clean pass sheet at every stage suggests the previous keeper kept basic consumables and emissions within limits. A buyer should still commission an independent inspection of suspension bushes, coil springs, and brake disc wear given the car's age and all-wheel-drive layout. The MOT record flags no corrosion or structural concerns, yet DVSA tests do not strip components. Verify the 2023 failure anomaly with DVLA to confirm no suppressed defect. Given the absence of advisories across four passes, previous ownership appears disciplined on statutory upkeep. The low defect count implies no skipped tyre or wiper replacements that commonly trigger minor fails. Treat the clean sheet as a positive, but confirm service history matches the mileage gaps before purchase.
