I can't see her lifting, carrying and setting the roof in the trunk by herself. Hence the photos don't show that. Marketing people always make things look easy and better than they really are.
It is funny, I was thinking about this today. I put my roof on in the garage. My garage door only has 4 panels so it is not too tall.
Making the clearance for me to lift the roof fairly small, but I was careful and did it.
I can see where the PO must have dropped it a few times. My corners are chipped and there is a nice crack over the driver's head.
