2015 Maserati Quattroporte 3.0L Diesel · NB11 BOS

The Maserati Quattroporte holds a valid MOT issued on 29 September 2025 at 68,282 miles, but the maintenance trend is mixed rather than consistently improving. The September 2025 test passed only after two consecutive failures in the same month, indicating that basic lighting, wiper, and braking faults were corrected at the last minute. A recurring advisory for slight play on the offside front track rod end ball joint persists across every test from March 2024 through September 2025, suggesting a worn component that has been monitored rather than replaced. Front brake discs have been flagged as worn, pitted, or scored at every inspection since March 2024, and the rear brake discs deteriorated from a minor advisory in March 2024 to seriously weakened by September 2025, pointing to progressive neglect of the braking system before the most recent pass. The mileage progression reveals a notable gap between March 2024 at 55,370 miles and September 2025 at 68,121 to 68,282 miles, representing roughly 12,900 miles covered in about eighteen months. That equates to approximately 720 miles per month, which is broadly consistent with the vehicle's lifetime average of around 6,200 miles per year for an eleven-year-old executive saloon. The record shows no evidence of exceptionally rapid accumulation or prolonged standing, though the clustering of three tests within three weeks in September 2025 suggests the owner was working through a list of defects to secure a pass rather than maintaining the car continuously. A buyer should pay close attention to the front suspension and steering linkage. The persistent advisory for slight play on the offside front track rod end ball joint, present at every test since March 2024 and previously flagged as excessive play during the March 2024 failure, indicates a component approaching the end of its service life. The braking system warrants a thorough inspection. Front brake discs have been repeatedly flagged as worn, pitted, or scored, and the rear discs progressed from a minor advisory to seriously weakened condition before the September 2025 pass. Rear brake linings were also found below 1.5 mm in September 2025, meaning the braking hardware has been run hard and replaced reactively rather than proactively. A physical inspection should verify whether the discs and pads now fitted are genuine or pattern parts, and whether any calipers are binding or showing uneven wear. Tyre condition has been a recurring failure point, with multiple tyres worn to or below the 1.6 mm legal limit across both axles in March 2024, suggesting the previous owner deferred basic consumable replacements. A close check of tyre age, sidewall condition, and alignment would be prudent.
