2021 Mercedes-Benz GLC 300 AMG LNE Prem + DE 4M A 1.9L Electric diesel · FX21 SWO

The most recent MOT test for this 2021 Mercedes-Benz GLC 300 AMG LNE PREM + DE 4M A was completed on 2026-04-04 and resulted in a PASS. This indicates that the vehicle currently meets the minimum safety and emissions standards, but it is important to note that the overall maintenance trend over the past few years has been consistent with the manufacturer’s expectations. The absence of any defects recorded in the three most recent MOTs suggests a stable service history, though the cumulative effect of regular use should be monitored. The vehicle’s age and mileage—48,129 recorded miles over approximately 5 years—align with typical wear patterns for its class, though the annual usage rate of around 9,626 miles per year is reasonable for a mid-range luxury sedan. The recorded mileage, while not exceptionally high, reflects a usage profile that could contribute to gradual component fatigue. At this stage, the risk of premature wear on critical systems such as the suspension, brakes, and drivetrain is moderate. The suspension bushes and coil springs should be inspected for any signs of binding or excessive play, while the brake discs and calipers need checking for corrosion or uneven wear that could affect stopping performance. The 12V battery should also be tested for health, as age-related degradation can impact electrical systems and lighting. Given the vehicle’s clean MOT record, the buyer should expect routine servicing intervals to remain effective. For a buyer approaching the end of the service book, it is advisable to conduct a thorough visual and tactile inspection of tyres, checking for cracks or perishing patterns that may indicate internal damage. Listen for any clunking or irregular noises during braking, which could signal worn brake pads or disc issues. Fluid levels and condition should be verified, especially brake fluid, coolant, and power steering fluid, as these are prone to degradation over time. Additionally, verifying service book stamps and mileage markers will confirm the vehicle’s maintenance history. If the MOT history remains clean and the mileage is within expected ranges, the car should perform reliably, but proactive checks are essential to catch any developing faults before they become serious.
