I would have put my seat down more if i could, but really the 400 was big enough for me (being 6"6). I havent spent much time driving 200's so no idea if id get seriously cramped sitting in one for a long time, have to ask someone else about that.
The standard rover sunroof thing doesnt help either, takes a few inches out of the headroom.
I'm 6' 2', my wife has a ZR with sunroof, I fit in fine although the driving position is pretty high. I note previous comments about height adjustable seats, my experience with these is that they do not go any lower than the fixed height seats.
If it was my car I might try and do something about the seat height it is and has been for many generations of the 200/400 honda based cars far too high.
I'm 6". More recently I've noticed the driving position in my car is not ideal. I've got long legs and have to have the seat quite far back, needless to say people tend not to like sitting behind me. My cars got height adjustment on the drivers seat, it could just do with being slightly lower imo.
Reading a few reviews on the ZR, one of the main complaints has always been the driving position.
