2021 Mercedes-Benz GLB 200 AMG Line Premium Auto 1.3L Petrol · LP14 LMP

The most recent MOT on 5 January 2026 was passed with no recorded defects, indicating that the vehicle currently meets the statutory safety and emissions standards. However, the preceding two tests show a pattern of advisory items relating to tyre condition and rear brake pad wear, suggesting that while the car has avoided outright failures, its consumables are approaching the end of their service life and will require attention in the near term. At 74 257 miles on a 2021 model the average annual mileage works out to roughly 14 800 miles per year, which is considerably above the typical UK average for a family SUV. This level of utilisation accelerates wear on the suspension bushings, steering components, drivetrain bearings and the braking system, and it also means the tyre tread and sidewalls have been subjected to a higher number of load cycles. There is no indication of long periods of storage, so the wear is likely to be genuine rather than perishing from age alone, but the high mileage does increase the probability of hidden fatigue in the coil springs and dampers. Prospective buyers should give the front tyres a thorough visual and tactile inspection. The advisories from 2024 and 2025 point to edge wear and early cracking, so any signs of sidewall bulging, dry rot, or tread depth below 3 mm will necessitate immediate replacement. On a test drive listen for any thumping or vibration that may indicate uneven tyre wear or a developing wheel balance issue. The rear brake pads were flagged as thin at 2 mm a year ago; verify the current pad thickness and inspect the discs for scoring, glazing or excessive rust, as the pads may now be at or below the minimum safe thickness, which could lead to reduced braking performance or pedal pulsation. Given the vehicle’s age and mileage, also examine the suspension components for any looseness, cracked rubber bushings or leaking shock absorbers, and check for any audible clunks when traversing bumps. Inspect the 12‑volt battery for corrosion on terminals and assess its state of charge, as a five‑year‑old battery may be nearing the end of its service life, especially if the car has seen periods of low usage. Verify that the coolant, brake fluid and engine oil have been changed in accordance with the manufacturer’s calendar intervals, as fluids degrade over time regardless of mileage. Finally, request a full service history and look for evidence of regular oil changes, filter replacements and any previous corrective work on the drivetrain, as this will give confidence that the high‑mileage vehicle has been maintained to a standard befitting its premium AMG‑Line specification.
