2021 Mercedes-Benz GLC 300 AMG Line Prem + D 4M A 1.9L Diesel · LN71 HSG

This Mercedes-Benz GLC 300 presents a clean bill of health on its most recent MOT, passing on 9 September 2025 at 25,410 miles with zero defects recorded. The maintenance trend is stable and positive. Two consecutive passes with no advisories or failures suggest the vehicle has been kept in good mechanical order, with no recurring faults or emerging deterioration patterns to flag. The mileage profile is notably low for a 2021-registered vehicle, averaging just 5,082 miles per year. Between the September 2024 test at 17,795 miles and the September 2025 test at 25,410 miles, the car covered 7,615 miles in twelve months, which is a meaningful uptick from the prior years of very light use. This shift from prolonged low activity to more regular driving is generally beneficial, as diesel engines like the GLC 300's benefit from consistent use to prevent DPF clogging and moisture-related corrosion in the exhaust and intake systems. The gap between the two recorded tests is exactly one year, so there are no suspicious mileage anomalies or long undocumented periods. Despite the clean MOT record, a buyer should still conduct a thorough in-person inspection focused on areas that MOTs do not fully stress-test. Check the condition of the suspension bushes, coil springs, and shock absorbers for perishing or weeping, as low-mileage vehicles can suffer from dry rot due to infrequent use rather than wear. Inspect the brake discs and pads for surface corrosion, which can develop quickly on a car that sits unused for extended periods. Examine the exhaust system and DPF health, particularly ensuring the diesel particulate filter regenerates properly under the new ownership pattern. Finally, look for any signs of structural corrosion on the underbody and around load-bearing mounting points, as the 4Matic drivetrain and AMG Line suspension components warrant close scrutiny given the vehicle's premium positioning.
