Hi everyone, When I ordered my Model S, it came with the standard White Alcantara Headliner as I didn't want to upgrade to the Premium Interior Package to get the black (and the rest of the items in that add-on didn't seem worth the value). I'm now wondering if it's possible to retrofit the headliner from the white to the black. My Model S has the panoramic roof and I've popped up a few of the panels to run dashcam/power cabling so I wonder the rest of the panels can pop off as easily. My questions: Has anyone done a retrofit like this? Has anyone had it done via Tesla at the Service Center? If so, how much was it? Would it be crazy to get the parts (whether somehow directly through Tesla or from a salvage) and do it myself? Has anyone done this aftermarket? How close to OEM is it? How much? Any shops in SoCal? I did some searching on the forums, though I had been unable to find any conversation about this topic, so forgive me if it's out there and I didn't stumble across it.
