While driving at low speeds, gently apply the brakes to feel for any judder, as the W212 can occasionally show wear in the front suspension bushings or control arms which may impact steering precision over time.
Check this by idling the engine in 'Park' and listening carefully for a slight rattle upon startup; the M272 or M276 V6 engines in this era are robust, but it is always wise to ensure the timing chain tensioners have been monitored throughout the vehicle's life.
While cruising on a highway, listen for any wind noise around the door frames or seals, as the rubber seals on a vehicle of this age may eventually lose some of their original suppleness.
Check this by operating every electronic button, especially the COMAND infotainment system and seat adjustments, to ensure all servos and modules are responding as intended.
A point where standard maintenance items like spark plugs and auxiliary drive belts often come into focus.
Usually the time to inspect suspension components and verify if the transmission fluid has been serviced.
Consider having a specialist review the engine mounts and cooling system health to ensure long-term reliability.
Keep a dedicated file for service records, as a documented history is one of the best indicators of a well-loved Mercedes.
Ensure the transmission fluid has been changed at recommended intervals to keep those shifts smooth as silk.
Check the coolant levels and the condition of the radiator hoses during your annual service to keep the engine running at its happy temperature.
Keep the cabin air filters fresh so the interior stays smelling like a proper executive lounge.
Regularly treat the leather upholstery with a quality conditioner to keep the seats feeling soft and supple.
Estimated repair costs if issues arise
If your model is equipped with Airmatic, the air struts or compressor may eventually reach the end of their service life. Future Budget Planning: You might want to set aside funds for potential replacement of these units to maintain that signature smooth ride.
These rubber mounts are designed to absorb engine vibration. Over time and many kilometers, they can compress, leading to increased cabin vibration at idle. Future Budget Planning: It is common to consider replacing these as part of a long-term refresh to restore that 'brand-new' smoothness.
Plastic components in the cooling system can become brittle over many years of heat cycling. Future Budget Planning: If you notice any faint sweet smells or small marks under the car, you might eventually need to budget for a proactive replacement of hoses or the thermostat housing.
