My sister took delivery of her 08 MB C350 a few weeks ago and the thing I liked most about her car(Aside from foglights that actually work, sideview mirror signal lights and a few others) was the 6 CD/DVD changer. I was wondering if it would be possible to change the changer in our cars to the changer in the new C350...

Because that'd be pimp. But then... I have a feeling that it's almost impossible.
