Hello, I just bought a c63s and it has a clunking noise that is driving me nuts! The car has 200 miles and is currently being held at the dealership trying to figure out what is wrong… so far they told me the sound is coming from the transmision. Hopefully someone here have had the same issue and was able to fix it. Thank you
