Listen carefully for any subtle 'thud' or metallic rattle from the suspension over uneven NZ road surfaces, as some X247 models can experience premature wear on stabilizer bar links.
Operate the MBUX infotainment screen and touchpad while idling; ensure there is no flickering or lag, as software-related glitches have been noted in early production units.
Accelerate firmly from a standstill to check for any hesitation or 'jerky' shifts in the 8-speed dual-clutch transmission, which is characteristic of this gearbox type in low-speed stop-start traffic.

A key point to inspect the 4MATIC all-wheel-drive system components and potential spark plug replacement to maintain fuel efficiency.
Ensure the Service A and Service B history is complete, ideally stamped by a Mercedes-Benz dealer or a reputable specialist.
Verify the coolant levels and check for any signs of residue, as the cooling system is critical for the turbo-charged inline-4.
Regularly treat the leather or MB-Tex upholstery with a quality conditioner to prevent cracking under the harsh NZ sun.
Keep the cabin air filter fresh; it makes a noticeable difference in interior air quality, especially if you do lots of motorway driving.
Check tyre tread wear across the full width, as the 4MATIC system can sometimes lead to uneven wear if alignment is neglected.

While the transmission is robust, refreshing the fluid is vital for smooth gear changes. Depending on your driving style, you might eventually need to budget for this specific service to keep the shifts crisp.
In cars of this age, it is common to consider the longevity of cooling components. If the water pump shows signs of weeping in the future, it is best to replace it preventatively to avoid engine overheating.
New Zealand's variable road surfaces can be tough on suspension. If you notice a loss in ride quality over time, budgeting for a refresh of the front control arm bushings can restore that 'new car' feel.
