With the engine fully warmed up, listen closely for a rhythmic 'ticking' sound at idle; while this can be a characteristic of flat-six engines, it is worth monitoring to ensure it doesn't transition into a deeper knocking sound.
Cycle through every gear while driving on a quiet road to ensure there is no reluctance or crunching when shifting, particularly into second gear, as this can indicate wear on the synchros.
Before moving off, check the coolant reservoir area in the front trunk and look under the car for any signs of dampness, as cooling system plastic components can become brittle over time.
Operate the electric windows and the rear hatch release multiple times; these rely on microswitches that may occasionally need adjustment or cleaning due to the age of the vehicle.
Usually marks the point where suspension bushings and engine mounts might start showing their age, impacting the car's sharp handling feel.
A common window for considering the condition of the clutch and flywheel if the vehicle has seen significant urban driving.
Consider having a specialist inspect the water pump and serpentine belt, as these are vital for cooling system reliability.
Check the service history for regular oil changes using high-quality synthetic lubricants, as the M97 engine thrives on fresh oil.
Verify that the brake fluid has been flushed every two years to maintain pedal feel and protect the ABS system.
Ensure the cabin air filter has been changed recently to prevent debris buildup and keep the interior ventilation fresh.
Inspect the under-body plastic shielding to ensure all fasteners are present, which helps keep the underside protected from road grit.
Confirm that the spark plugs and ignition coils have been serviced according to the schedule to ensure smooth combustion.
Estimated repair costs if issues arise
While the 2.7L M97 engine is less prone to issues than earlier units, it is common to consider a preventative inspection or upgrade during a clutch change. It provides peace of mind for the long-term owner.
If the steering feels less precise than a Porsche should, you might eventually need to budget for new control arms or dampers to restore that iconic 'factory fresh' handling.
As part of long-term ownership, these items are often replaced as a package to ensure the cooling system remains efficient and protects the engine from thermal stress.
