Just got my P85D last week. Love it. When I picked it up I noticed the window opens slightly when you open the door. The DS explained this was done to make it easier to close the door by letting air out. Otherwise, the car is sealed so tightly, it is difficult to close. Amazing attention to detail. I find that the door is still slightly difficult to close and it becomes easier if I open the window. I'm curious whether this is the case for others and we should ask to have the window automatically open a bit more. By the way, an unrelated tidbit I learned friends from the DS is that on the P85D, the chargeport can be opened by pushing in slightly on the front of it.
