4.0L V8 Twin-Turbo - C63 AMG
Petrol
Listen for any rhythmic ticking or chain rattle during a cold start; it is worth noting that the timing chain tensioners can eventually show signs of wear in higher mileage examples.
Observe the gear shifts in Sport+ mode; while the MCT gearbox is robust, check that the shifts feel deliberate and smooth, as occasionally the clutch packs may require recalibration over time.
Check the infotainment screen and climate controls; like many German performance vehicles, the complex electronic modules may experience intermittent connectivity issues as the vehicle ages.
Feel for any vibration through the steering wheel at highway speeds; the suspension components are quite performance-focused, and it is common for the front control arm bushings to eventually require inspection for play.
Usually a great time to evaluate the cooling system components and spark plug health.
Often the point where a full transmission fluid and filter service is recommended to maintain that crisp shift quality.
A common interval to check the integrity of the engine mounts and any ancillary belt pulleys.
Ensure the logbook shows regular oil changes using the manufacturer-specified high-performance synthetic oil.
Verify that the brake rotors and pads have plenty of life left, as these high-performance items are designed for stopping power rather than longevity.
Take a peek at the tyre tread depth across the inner and outer edges to ensure the alignment is tracking straight.
Confirm the air conditioning system is blowing cold, as the compressors are working hard in our Kiwi summers.
Check for a consistent service history, ideally from an authorized Mercedes-Benz specialist who understands the specific demands of an AMG engine.
Estimated repair costs if issues arise
Given the stopping power required for the C63, these components naturally wear faster than standard C-Class models. You might eventually need to budget for a complete set refresh to keep the car performing at its best.
Depending on the car's history and road conditions it has faced, you might eventually need to budget for the replacement of electronic dampers to maintain the factory-standard ride quality.
In cars of this age, it is common to consider the preventative replacement of cooling system hoses and the water pump to ensure the 4.0L engine remains at optimal operating temperatures.
