THIS MUCH! (O_o)
You have to remove the interior panel, and all the screws and fasteners and clips along with it, without tearing the panel to get it off. Then you have to pry the handle free from its ball-and-socket mounting and pull it out. What should have been a 20 minute job for me became a 2 hour job over the course of two days. Mind you, this was just one panel.
I’ll be going after the second one after work today; but for now, have this Carrera Targa that’s parked at my work parking lot currently. :)
