Getting everything out of the car is pretty simple and I miraculously didn't break any tabs or clips doing so. However, the glue on the sunroof shuttles and the A-, B-, and C-pillars are monsters. Very very tough to remove with a brush drill attachment and it makes a massive mess of your work area. I also (unfortunately) decided to go with an a suede-like material and it just didn't have any stretch at all, which made it very difficult to get around all the contours.

Everything looks okay except for the corners around the pano sunroof... really bummed about it, but basically I had to make relief cuts for the material to even come close to wrapping around the lip of the headliner and there are pie shaped gaps that I need to fill somehow. It's never going to look perfect and honestly I'm not sure I can even reverse it now since the refreshed glue will be even more impossible to remove than the old stuff. In hindsight - I'd either get someone to re-cover it, or I'd use a regular headliner material because I didn't have any issues using that on my mini.
