Cycle through the Dynamic Select modes while stationary and driving; ensure the transmission shifts smoothly between gears without hesitation, as the 9G-TRONIC can sometimes exhibit quirks if the transmission fluid service history is incomplete.
Carefully inspect the frameless windows by opening and closing the doors; check that the auto-drop and seal mechanism operates flawlessly to prevent wind noise or water ingress at highway speeds.
Activate all MBUX infotainment features, specifically checking the touch-sensitive steering wheel controls and the central trackpad, as these are high-use electronic components that can occasionally become unresponsive.
Navigate over a series of speed bumps at low speed and listen intently for any suspension creaks or rattles from the front end, as these components work hard on our NZ roads and can show wear as they age.
Usually marks the first major service interval where transmission fluid and spark plugs are often recommended for replacement to maintain efficiency.
Consider a comprehensive inspection of the auxiliary cooling system and turbocharger intake piping, as high-temperature plastics can begin to show signs of aging.
Typical interval for professional inspection of the engine mounts and suspension bushings to ensure the refined ride quality remains intact.
Prioritize a pre-purchase inspection from an independent European car specialist who has access to genuine Mercedes-Benz diagnostic software.
Verify the digital service history (DSB) record; Mercedes-Benz keeps a centralized log, and a gap here is worth investigating.
Check the tire condition thoroughly; these cars are sensitive to tire compound, so look for matching, high-quality rubber on all four corners.
Ensure the AdBlue tank has been topped up at the correct intervals if applicable, as emission systems appreciate consistent maintenance.
Regularly treat the leather and interior trims with quality conditioners, as the cabin features many soft-touch materials that benefit from climate-appropriate care.

The CLS is a substantial vehicle, and the brakes are high-performance items. In cars of this age, it is common to consider that these components wear based on driving style, so budgeting for a premium set of discs and pads is a proactive step.
While reliable, the integrated screen technology is complex. If this component needs attention in the future, the estimated cost in NZ is higher due to the specialized nature of the hardware.
