I happened to be checking out a '13 SL63 the other week and noticed something nifty on the steering wheel. In place of where the black plastic "Airbag" plate is at the bottom of the wheel is a very nice aluminum AMG plate. It's not part of the wheel and I fiddled with it for a bit and looks like it just snaps in there. The C, CLS, SLK I know share the same wheel. Where can we get one of these AMG plates at? MB part # maybe, knowing them though they'll make you buy the whole wheel.

 

Someone on this forum got this for their car and did an entire DIY write up. You would think its an easy procedure but you basically have to take the whole steering wheel apart and it was something like $400 I think (I could be wrong about the price, but for what it is it is an expensive, albeit very nice, little mod)

EDIT: $300 plus $15 shipping off of EBAY

Good grief. Nevermind. From looking at it it looked like just a snap in piece.
