2009 Maserati Quattroporte 4.2L Petrol · RX09 CEJ

The vehicle presents a concerning roadworthiness profile with a clear trend of worsening structural integrity. While it passed its most recent test in August 2025 at 74,856 miles, this followed a significant failure just eight days prior. The tester identified critical structural defects involving excessive corrosion on the inner sills and seat belt anchorages, which had significantly reduced structural strength. Although the subsequent pass noted the corrosion was no longer considered excessive, the transition from a major structural failure to a minor advisory indicates that the chassis is reaching a state of advanced decay. At 17 years old, the recorded mileage of 74,856 miles represents an average usage of approximately 4,400 miles per year. This low mileage often suggests the vehicle has sat for long periods, which frequently accelerates electrolytic corrosion and the degradation of rubber components. The data shows a consistent increase of roughly 5,000 miles per year between 2023 and 2025, yet the low annual mileage has not protected the car from mechanical and structural failures, suggesting that the primary issues are environmental age rather than mileage-related wear. A physical inspection must prioritize the structural condition of the chassis and suspension mounting points. The history shows recurring issues with the front suspension, including track rod ends, anti-roll bar links, and a distorted nearside wheel. The buyer should verify that the repairs made to the inner sills after the 2025 failure were structural rather than cosmetic. Furthermore, the 2024 failure regarding high carbon monoxide emissions indicates potential engine management or catalytic converter issues that require a professional diagnostic check to ensure the powerplant remains operating within manufacturer specifications.
