2009 Mercedes-Benz G-Class 5.4L Petrol · GA55 AMG

The most recent DVSA MOT test on the 2009 Mercedes-Benz G-Class occurred on 2026-06-26, resulting in a passing grade. However, the vehicle’s MOT history reveals a pattern of recurring advisories and minor failures, particularly concerning the rear coil springs, front and rear tyres, and the central propeller shaft joint. While the latest test did not flag any major defects, the repeated corrosion of both rear coil springs—documented in multiple MOTs over the past five years—indicates a persistent structural issue that may compromise suspension integrity and ride quality over time. The presence of tyre wear advisories, including worn edges and tread depth concerns, suggests ongoing or historical neglect in tyre rotation or alignment, which could lead to uneven tyre wear, reduced traction, and premature tyre failure if left unaddressed. The vehicle’s recorded mileage of 157,955 miles at the time of this assessment aligns with a typical annual usage rate of approximately 9,291 miles, which is consistent with the age of the car. This mileage level does not indicate excessive wear beyond what is expected for a 17-year-old vehicle, though it does reflect sustained operational use rather than prolonged periods of inactivity. However, the MOT history does not show significant gaps in mileage accumulation, and the lack of a recent service record suggests the owner may not have prioritised routine maintenance. This could contribute to the observed wear on consumables like the central propeller shaft joint and the gradual corrosion of suspension components, which are more susceptible to degradation when not serviced at recommended intervals. To proceed with a thorough inspection, the prospective buyer should commence with a visual and functional assessment of the suspension system. The advisories regarding corroded rear coil springs warrant immediate attention, as rusted suspension elements can lead to premature failure, reduced handling stability, and potential road hazard risks. During a test drive, listen for abnormal clunking or rattling noises from the rear suspension, particularly when transitioning between rough and smooth road surfaces, as these could indicate loose or failing suspension bushes or springs. Additionally, check for uneven tyre wear patterns, which may suggest misalignment or improper camber angles, and inspect the tyres for signs of excessive edge wear or tread damage, as these are linked to the previous MOT advisories. The central propeller shaft joint’s severely deteriorated boot suggests a leaky or failing seal, which could result in oil loss and increased friction in the drivetrain; verify for oil leaks around the joint and listen for unusual grinding or whining noises during acceleration or cornering. For the buyer’s practical inspection, focus on the vehicle’s fluid levels and overall mechanical condition. Given the age and mileage, the 12V battery should be tested for charge capacity and terminals, as standing corrosion or prolonged disuse can lead to poor electrical performance. Inspect the brake system for signs of corrosion on discs or binding calipers, particularly on the near-side front brake, where the MOT may have noted potential inefficiency. Check the brake fluid reservoir for contamination or low levels, as brake fluid degrades over time and can cause spongy pedal feel or reduced braking efficiency. Finally, verify that the service history is up to date, especially for the propeller shaft joint replacement and any scheduled suspension or tyre maintenance, as these are critical areas of wear for a vehicle of this age and usage profile. If the owner lacks a service book, consider requesting one to ensure compliance with manufacturer-recommended intervals for fluid changes, filter replacements, and component replacements.
