I believe that the original 2008 C63 hood was steel so I assume that the fenders were too. When did MB start using aluminum? My '13 sedan front fenders, hood and gas filler cover are aluminum. I can't seem to find this info.

As far as I can tell using a magnet
Fenders Al
Filler cap is plastic
Hood skin is Al
Hood sub-structure/ frame is steel

Mine is MY 2009 built in 2008

Yea, I used a magnet too, Injenieur, to determine what isn't steel. So the gas door is plastic. Interesting. I just went out to the garage, popped the hood and checked the sub-structure with a magnet and it too appears to be Al with only the latches being steel. Maybe this is what SaphGreyC63 is referring to as '12 being the first year for the total hood assembly being Al? Anyway, thanks for the replies gentlemen and your C63 looks great Injenieur. Do you have any photos showing the wheel detail?
