a bench will never ever fit in a car, unless its a 4x4 or an mpv with the seats taken out or the bench has been taken completely apart (which usually never happens, due to throwing away instructions after building it).
also, if it is 200kg, of weights plus a bench thats about 2/3 people. so if you are taking it in a extremely big car, space the weight out a little, all in the boot wouldn't be a good idea.
the best option would be to borrow a van, someone you know must have access to or own a van.
