I have a 2015 Model S with Piano Black decor and actually like it a lot. But I like the figured Dark Ash on newer cars a lot more. I can get the decor pieces, but my question is does anyone know if the new decor can be easily retrofitted? As in, no difference in clips/screws compared to the decor in my car? Also, has anyone done this themselves? How long is the job, how easy? Supplementary question to that would be, if I get the parts. Would a service center be willing to install them? And if so what would that run me? Any answers would be greatly appreciated, thanks!
