the door handle needs to be shifted to the left or right before it cfan come out.. i cant remember which.. just try sliding it either way as there are 2 "L" shaped bits that hook into the door..
also the other tought bit is the window winder which has a "U" shaped clip behind it..
ALSO, be careful pulling off the trim itself as they are pretty wak (were in my old CSi anyway) be carful with each clip as they snap off the backing easily and are a shit if they are busted...
