2010 Maserati Quattroporte 4.2L Petrol · YJ60 AOG

The Maserati Quattroporte holds a current, valid MOT following a clean pass on 27 April 2026 at 43,125 miles with zero defects. That result is significant. Just thirteen days earlier, on 14 April 2026 at 43,118 miles, the car failed with a serious corrosion-related defect on the offside rear upper suspension mounting area, specifically the upper control arm bracket, flagged under reason 5.3.6 (a) (ii) as adversely affecting vehicle control. The rapid turnaround suggests the fault was repaired promptly, and the subsequent clean pass indicates the structural issue has been resolved. The overall maintenance trend is therefore improving, though the nature of the defect warrants careful scrutiny. The mileage profile is notably low for a 2010 vehicle, averaging roughly 2,695 miles per year over sixteen years. The record shows a gap of nearly fourteen months between the December 2022 pass at 35,540 miles and the January 2024 pass at 37,381 miles, a gain of just 1,841 miles. A further two-year gap follows before the February 2025 test at 39,968 miles, adding 2,587 miles. The jump to 43,125 miles by April 2026 represents a more active period with 3,157 miles covered in roughly fourteen months. This pattern points to prolonged periods of low use punctuated by occasional bursts of driving, which can be harder on seals, bushes, and brake components than steady mileage accumulation. The recurring theme across the record is suspension wear and structural corrosion. The February 2025 test flagged a worn nearside front upper suspension arm pin or bush under advisory, and the April 2026 failure centred on corrosion of a rear suspension mounting point. Both relate to the same system and suggest the car has spent time exposed to conditions that promote corrosion, possibly standing for extended periods. A buyer should inspect all suspension bushes, ball joints, and subframe mounting points for further corrosion or deterioration, paying close attention to the repaired offside rear upper control arm bracket. The underbody, sills, and suspension turrets should be examined with a torch and, ideally, the car raised on a lift to verify the integrity of the repair and check for additional hidden corrosion. Brake components deserve attention given the low-mileage, stop-start usage pattern, which can lead to surface corrosion on discs and binding calipers even when pad life remains high. Tyre age and sidewall condition should also be checked, as rubber degrades with time regardless of tread depth. The clean April 2026 result is reassuring, but the severity of the preceding failure means a physical inspection of the chassis and suspension is essential before purchase.
