Observe the Airmatic suspension closely. Listen for any persistent whirring or hissing sounds while the car is idling or parked, as the compressor may occasionally struggle on high-mileage examples of this age.
Check the infotainment screen and touchpad response. Ensure the Command system boots up without flickering and that the controller registers inputs accurately, as the electronic units can sometimes show signs of wear over time.
Perform a cold start and listen to the V6 engine's idle. In cars of this vintage, it is helpful to ensure the engine settles smoothly into a steady rhythm, keeping an ear out for any abnormal rattling or metallic resonance.
Evaluate the 9G-TRONIC transmission shift quality. While driving at varying speeds, ensure the transitions between gears feel seamless; slight hesitancy can occasionally occur in these units depending on the age of the transmission fluid.

A common point where secondary cooling system components, like the water pump or hoses, may require a preventative review.
The typical interval to assess the health of the drivetrain mounts and ensure the transmission service records are up to date.
Ensure regular engine oil changes are performed at 10,000km or 12-month intervals to keep those twin turbos happy.
Keep an eye on the cabin air filter replacement to ensure the climate control system stays fresh and airflow remains strong.
Prioritize a brake fluid flush every two years to maintain that sporty stopping power and protect the ABS module.
Regularly inspect the panoramic sunroof tracks and seals to keep them clear of debris, ensuring smooth operation in our variable NZ weather.
Keep the battery health monitored, especially if the vehicle sits for extended periods, as these electronic systems perform best with a strong, consistent charge.
Estimated repair costs if issues arise
If the vehicle sits lower on one corner after sitting overnight, you might eventually need to budget for strut or bellows maintenance to restore that legendary ride comfort.
To keep the 9G-TRONIC gearbox shifting smoothly, it is worth planning for a full fluid and filter service if there is no record of it in the logbook.
Given the performance nature of the GLE450 AMG, the brakes are substantial. Depending on your driving style, you might eventually need to budget for these as they reach the end of their service life.
