4.2L V8 (F136) - Executive GT/Sport GT
Petrol
Test drive task: Shift between R, N, and 1st gear while stationary on a slight incline. | Observation: Observe the smoothness of the DuoSelect (automated manual) transmission; hesitation or unusual clunking could suggest the clutch assembly is reaching the end of its typical lifespan.
Check this by: Opening the bonnet with the engine running and listening near the front of the V8. | Observation: Listen for any rattle from the variable valve timing (variator) system, as these early M139 engines can sometimes develop a rhythmic ticking sound as mileage increases.
While driving: Find a quiet road and steer gently from left to right. | Observation: Be mindful of any 'wallowing' or uneven firmness in the suspension, as the Skyhook active damping system relies on sensors that may eventually require recalibration or individual strut attention.
Check this by: Inspecting the interior switchgear and center console buttons. | Observation: Note any 'tackiness' or peeling of the soft-touch plastics, which is a common cosmetic evolution for Italian luxury vehicles of this era due to New Zealand's UV exposure.
Usually marks the point where the initial suspension bushings may begin to show minor play.
A common window where the clutch life on DuoSelect models requires a professional inspection to avoid flywheel damage.
The time to ensure the water pump and cooling system components have been serviced to maintain optimal engine temperatures.
Verify the full stamped service history, ideally prioritizing invoices from Maserati-specialist workshops.
Check for consistent use of high-quality engine oil, as the F136 V8 performs best with regular, timely changes.
Inspect the underside for any signs of fluid weeping from the transaxle assembly.
Confirm that the battery is in peak condition, as these electronics can behave uniquely if the voltage drops below optimal levels.
Check the condition of the rear tyres, as the Quattroporte's chassis balance can lead to specific wear patterns if the wheel alignment hasn't been recently checked.
Estimated repair costs if issues arise
As this is an automated manual, the clutch is a wear item much like a standard manual car. If the biting point feels high or the shifts become sluggish in the future, you may need to budget for a full clutch kit replacement.
These active dampers provide that signature Maserati ride quality. Depending on the car's history, you might eventually need to budget for replacing individual struts if they begin to weep fluid or lose electronic communication.
If the engine develops a distinct rattle upon cold start, it is wise to consider a preventative inspection of the variators. Addressing this early keeps the V8 running at its peak potential.
