Petrol
Engage the DuoSelect or ZF automatic transmission through all gears while warm; check for any hesitancy or clunking during shifts, as hydraulic actuator issues can be common in models of this age.
Accelerate firmly in a safe area to listen for any ticking or rattling from the F136 V8 engine; early chain tensioner wear is something to keep an ear out for.
Operate every interior electronic feature, including the infotainment and seat adjustments; these electrical systems can occasionally exhibit quirks due to aging wiring harnesses or control modules.
Perform a tight steering maneuver at low speeds while listening for suspension clicks; the complex double-wishbone suspension components may eventually show signs of wear given our varied NZ road surfaces.
Usually marks the point where the first major suspension bushing inspection is highly recommended to maintain that trademark handling.
Common timeframe to consider a comprehensive check of the cooling system components, including hoses and the water pump.
A significant point to verify the status of the auxiliary belt system and ensure all high-pressure fuel components are performing within expected parameters.
Prioritize a pre-purchase inspection with a specialist who has experience with the M139 platform.
Verify that the engine oil has been changed at least annually, regardless of the distance covered, using the manufacturer-specified synthetic grade.
Check the service history for documented brake fluid flushes to ensure the health of the braking system.
Examine the tyre wear patterns to ensure the alignment is correct, as the Quattroporte's performance geometry can be sensitive to uneven settings.
Ensure all recall history has been addressed, which your specialist can verify using the VIN.
Estimated repair costs if issues arise
If the vehicle is equipped with the automated manual, the clutch is a consumable item. Depending on your driving habits, it is wise to keep a buffer in your future budget planning for eventual replacement.
With the Quattroporte's focus on handling, these components do a lot of work. You might eventually need to budget for a refresh of the front or rear suspension arms to restore that 'factory fresh' ride quality.
While the F136 is a soulful engine, the variable valve timing system can eventually require adjustment or attention to maintain smooth idle and peak performance. It is sensible to keep this on the radar for long-term ownership.
