2005 Maserati Quattroporte 4.2L Petrol · OO05 MAS

This Maserati Quattroporte presents a generally sound mechanical picture, though the maintenance trend is one of gradual, low-level deterioration rather than active neglect. The most recent test on 5 November 2025 at 50,273 miles passed, but the tester flagged corrosion within the rear subframe mounting prescribed area. While assessed as not excessive at that time, this advisory has appeared in the preceding year's test as well, suggesting a slow-onset structural concern that warrants ongoing monitoring rather than immediate alarm. The vehicle has covered roughly 2,394 miles per year over its 21-year life, which is notably low. The MOT record confirms this restrained usage, with only 532 miles added between the November 2021 and November 2022 tests, and a similarly modest 182 miles between October 2024 and November 2025. Long periods of standing can accelerate certain failure modes, particularly seal degradation, brake disc surface corrosion, and localised rust on chassis components, even when overall mileage remains minimal. A prospective buyer should focus a physical inspection on the subframe mounting points front and rear. The 2024 test at 50,171 miles noted subframe corrosion both front and rear, and the 2025 test at 50,273 miles specifically highlighted the rear subframe mounting area. Surface corrosion can be cosmetic, but prescribed area corrosion on a 20-year-old saloon demands a thorough underside examination with a torch and probe to verify structural integrity. The rear inner brake discs were flagged as worn, pitted, and scored in the November 2021 test at 49,749 miles, yet no further brake defects have appeared in the subsequent four tests, indicating either replacement or light use keeping wear within limits. Still, a test drive should confirm the handbrake holds firm on a gradient and the pedal feels firm without judder. Tyre condition has been a recurring minor theme. The offside front inner edge was flagged in both 2021 and 2023, and the offside rear tyre showed slight damage in 2024. These advisories point toward possible alignment or suspension bush wear causing uneven scrub, rather than simple neglect. A buyer should check the inner sidewalls closely and have the four-wheel alignment inspected, particularly given the car's low annual mileage, which can mask gradual wear on bushes and joints that degrade with age rather than distance.
