I did it in the summer with a saloon. You have to take one of the front seats out in order to lower the roof lining sufficiently to the correct angle (approx. 45 degrees) to use the widest part of the door aperture. It won't clear the seat base even with the back of the seat fully lowered. I removed the drivers seat as I was working on that side of the car, but the lack of a steering wheel on the left side may give a bit more jiggle room if it is done from that side.
A extra pair of hands is useful to help support it whilst getting out, as it is easy to damage the front of the headlining at it weakest point by the sunroof controls cover / interior light cut out. Although it has a strengthening plate, it is easy to bend it whilst taking it out.
Mine seemed to come out easier than putting it back in, but a helper is definitely advisable.
