.............compare the distance between the trailing edge of the door and the beading where the rear wing meets the body between cars, and the long door/shorter gap is obvious. Longer doors make entry and egress easier, so if you are taller, then a long door car may be the better option for you. Remember also that two different door lengths results in two sets of side-screen dimensions, and the side-screen shape and seal design has evolved over time. This is yet one more reason why Morgans can look so different from each other........................
