The slk is very flat as well, as far as the ac/radio piece goes there are no angled edges, the holes for the AC dials are much larger. The hazard switch section is not curved so the xfire buttons would be popping out super far. The shift surround again is flat and does not have the same shape. I think the only way it could be done would be to find a way to replace the entire center console not just the trim and find a way to blend it into the crossfire dash where they would connect. The buttons and AC controls however can be used in the xfire. There are plenty of options if your looking to change the silver color of that's what you are looking to do.
