2007 Maserati Quattroporte 4.2L Petrol · LJ07 EYP

The 2007 Maserati Quattroporte presents a generally stable and improving maintenance trend, culminating in a fully clean pass on 9 September 2025 at 46,551 miles with zero defects recorded. This is a significant improvement over the preceding years, where recurring advisories and failures were logged. The most serious structural concern, a front chassis corrosion failure near the exhaust front pipe noted on 8 July 2024 at 41,486 miles, appears to have been rectified, as the subsequent tests in October 2024 and September 2025 show no further mention of structural integrity defects. The trend suggests a period of neglected underbody condition has been addressed. The mileage pattern reveals a notable anomaly that warrants closer scrutiny. Between the 8 July 2024 failure at 41,486 miles and the 11 July 2024 pass at 53,804 miles, the odometer jumped by over 12,000 miles in just three days, which is physically implausible and strongly suggests a data entry error or odometer discrepancy. Ignoring this irregularity, the vehicle has covered roughly 4,373 miles between the 2024 October test and the 2025 September test, indicating continued but light use. The overall average of approximately 2,450 miles per year remains exceptionally low for a nineteen-year-old vehicle, pointing to prolonged periods of inactivity rather than consistent daily driving. Prospective buyers should pay particular attention to the front suspension and underbody structure during any physical inspection. The 2024 July failure specifically cited excessive corrosion to the nearside front suspension mounting area on the chassis, a critical structural point. While the 2025 clean pass is encouraging, the history of distorted front road wheels across multiple tests in 2024 suggests possible kerb impacts or underlying suspension geometry issues that may have caused uneven tyre wear. The intermittent tyre pressure monitoring system warning lamp, flagged in both July 2024 tests, could indicate a slow puncture, faulty sensor, or a wheel rim distortion affecting the seal, all of which should be verified. The recurring advisories on front anti-roll bar linkage play and outer tyre damage, though minor in isolation, point to a vehicle that has not always been maintained to a meticulous standard. A thorough inspection of all suspension bushes, ball joints, and subframe mounting points is advisable, alongside a detailed underbody examination for fresh welding or applied sealant that might mask the previously failed corrosion. The clean 2025 result is a positive indicator, but the erratic mileage data and history of structural corrosion mean a pre-purchase inspection by a specialist familiar with Maserati construction is strongly recommended.
