2021 Mercedes-Benz GLB 220 AMG Line Prem + D 4M A 1.9L Diesel · LS21 OKR

The vehicle is currently roadworthy having passed its most recent MOT in March 2026 at 23,578 miles. While the vehicle meets minimum legal standards, the maintenance trend shows a concerning recurring pattern regarding tyre condition. The transition from a clean record in 2024 to multiple advisories for perishing in the subsequent two years indicates that the rubber is failing due to age and lack of use rather than wear. The mileage profile is notably low for a five-year-old vehicle, averaging approximately 4,700 miles per year. The data shows consistent, slow progression from 16,330 miles in March 2024 to 20,814 miles in March 2025, finally reaching 23,578 miles by 2026. This low usage often suggests the car sits stationary for extended periods, which explains the premature chemical degradation of rubber components like tyres and potentially suspension bushings before the tread depth reaches legal limits. A buyer must conduct a thorough physical inspection of all four tyres to check for sidewall cracking and dry rot. The 2025 test flagged both front tyres and the nearside rear for perishing, and the 2026 test confirmed continued damage to the front pair and nearside rear. This suggests the previous owner has neglected replacing essential consumables despite clear advisories. Additionally, inspect the brake discs for surface corrosion or pitting, as low-mileage vehicles frequently suffer from oxidation when the rotors are not used frequently.
