Check the CVT transmission smoothness | Description: While driving, pay close attention to any jerking or hesitation during acceleration, as these units can occasionally develop wear that affects shift quality.
Test the steering feel at low speeds | Description: Check this by performing a full lock-to-lock turn in a parking space to ensure the electric power steering motor is silent and responsive without any 'notchy' feedback.
Evaluate the cabin electronics | Description: Test the infotainment and instrument cluster displays; in cars of this age, it's common to consider that pixel failure or minor electrical gremlins can appear over time.
Listen for suspension clunks | Description: While driving over speed bumps, listen for any knocking sounds from the front end, as the bushes and drop links are common wear items on NZ roads.
Usually a good time to check the serpentine belt and tensioner assembly for signs of age.
Often the point where original suspension components like struts and control arm bushings may require a refresh for optimal comfort.
Consider having a specialist inspect the CVT fluid condition and the cooling system hoses for signs of brittleness.
Verify the service history logbook for regular oil changes using the correct Mercedes-approved synthetic lubricant.
Check the condition of the under-bonnet plastic covers to ensure they are secure and not rattling.
Inspect the coolant reservoir for any signs of discolouration or oil contamination.
Confirm the operation of all windows and the sunroof if fitted, as the runners can occasionally accumulate dust.
Ensure the air conditioning blows cold, as the compressor is a hardworking component in this model.
Estimated repair costs if issues arise
If the transmission begins to show symptoms of wear, you might eventually need to budget for a specialized fluid flush or, in more complex cases, a valve body repair to keep the car driving smoothly.
Depending on the car's history and the types of roads it has traveled, you may eventually need to budget for replacing front control arm bushings to maintain that classic Mercedes ride quality.
If this component needs attention in the future, the estimated cost in NZ includes professional labour to access these parts, which can be a bit tight in the W169 engine bay.
