Looks great!
More info on the sill pieces?
I've also wondered if I could use a normal E9x 3 series console trim to ultimately delete the Power/EDC/DSC buttons. It gives you a larger shift boot which I actually think looks a bit cleaner. I hate Power mode so I don't use it. Car no longer has EDC shocks and if I really want DSC off I can do it through the controller and setup my M button to have it off.
What I have't been able to find is if they have a version meant for the LCI controller for those of us that do have NAV. Looks like it from some images but would likely require some testing. Would also need to find one in the same finish.
