Whassup?
I would never to that kind of swap, but that's just me. I just don't have the patience for it... S4?? I don't know.

But the interior should be a different story. I would suggest seeing what it looks like if you trade peices like: the door jam panels, vents, the console, the gauge cluster cover, and keep in mind I'm not that familiar with your interior. But just some thoughts.
