MASERATI QUATTROPORTE2006 · 4.2L PETROL

The 2006 Maserati Quattroporte presents a broadly stable mechanical picture, with no outright failures recorded since November 2019. The most recent MOT, conducted on 10 June 2025 at 64,148 miles, passed cleanly aside from advisories on both rear brake discs, noted as worn, pitted or scored but not seriously weakened. This is a minor surface condition rather than a structural or safety-critical defect. The trend since the failed test in November 2019 shows a clear improvement: the car has passed every subsequent test on its first presentation, suggesting the previous owner addressed the earlier faults promptly and has maintained the vehicle to a reasonable standard. The mileage profile is notably low for a twenty-year-old car, averaging roughly 3,207 miles per year. Between the November 2021 test at 63,690 miles and the June 2025 test at 64,148 miles, only 458 miles were covered across nearly four years. This points to very light recent use or extended periods of inactivity. A car standing for long durations can develop issues unrelated to mileage, including deteriorated rubber components, brake surface corrosion, and fluid degradation. The gap between 2021 and 2025 is significant, and a buyer should treat the low mileage as a double-edged indicator rather than an automatic positive. The recurring theme across the record is rear brake disc surface wear. This advisory appeared in November 2019 and again in June 2025, suggesting the rear discs are prone to scoring or corrosion, particularly if the car sees short trips or sits idle. The front brake fluctuation noted in the 2019 failure was resolved and has not returned, which is encouraging. Rear tyre condition has also been flagged multiple times, with tread wear and a cut noted in 2019 and near-limit wear again in 2020. This pattern implies the rear tyres may be wearing unevenly, possibly indicating alignment issues, suspension bush wear, or simply the car's weight distribution and drivetrain layout placing greater demand on the rear axle. A prospective buyer should focus the physical inspection on the rear braking system, checking disc thickness and condition beyond the surface scoring noted in the MOT. Suspension bushes, particularly at the rear subframe and trailing arms, deserve close attention given the repeated tyre wear advisories. Inspect all rubber components, including brake hoses and suspension bushes, for perishing consistent with a car that has spent extended periods stationary. Verify the condition and age of all four tyres, and check whether the spare has been maintained. The exhaust emissions failure in 2019 has not recurred, but a live emissions check during a test drive would confirm the catalytic converters remain efficient on a car of this age and type.
