2017 Mercedes-Benz GT 4.0L Petrol · 15 KAM

A pattern of long-term roadworthiness is interrupted by a recent advisory regarding tyre degradation, marking the first recorded defect in a sequence of clean tests dating back to 2022. While the vehicle has achieved consecutive passes without any recorded failures or mechanical defects since its inception, the most recent test on 24 March 2026 identified that both rear tyres are showing signs of cracking or perishing. This transition from a defect-free record to a specific advisory on rubber components suggests that while the primary mechanical systems have met inspection standards, the peripheral consumables are now reaching the end of their functional lifespan due to age. The vehicle's usage profile is characterised by exceptionally low annual mileage, averaging approximately 2,415 miles per year over its nine-year lifespan. With a recorded mileage of 21,734, the car has been driven significantly less than the UK average, which typically points to infrequent use rather than heavy mechanical strain. From a technical standpoint, this low-frequency usage often means that components like the braking system, suspension bushes, and drivetrain are subject to less frictional wear, but it also increases the likelihood of age-related degradation in rubber and seal components, as evidenced by the recent tyre advisory. A prospective buyer should focus their physical inspection on the condition of the tyres, specifically looking for deep sidewall cracking or any signs of uneven tread wear that might suggest alignment issues. Given the advisory on both rear tyres, a test drive should include monitoring for any vibration through the chassis or unusual road noise that could indicate the rubber has become too hard or brittle to maintain optimal contact with the road surface. It is also prudent to inspect the tyre sidewalls for any bulging or structural irregularities that may have developed during periods of inactivity. Beyond the tyres, the lack of recorded failures in the MOT history suggests that the suspension, steering, and braking hardware have not triggered any immediate regulatory concerns. However, because the vehicle has been driven so sparingly, a thorough check of the brake discs for surface corrosion or pitting is advisable, as low usage can allow moisture to affect the metal surfaces. During the test drive, listen for any rhythmic knocking from the suspension linkages or pulling to one side under braking, ensuring that the low mileage has not resulted in seized calipers or unevenly worn pads that were not captured during the static MOT inspection.
