I still have the black C43, i doubt i will sell that car anytime soon!!! If i keep it for long enough, eventually, I will look for an AMG 5.4L V8 out of an AMG55 and swap it into the C43, have RENNtech do the DME, and there we go, i have a C55!!! Please keep me posted if any1 of you come across any AMG55 motors!!
