As wrong as it is, that is just insane Merv.
Would be mad adapted to a standard length wheelbase and see what it looks like. Imagine interchangeable hardtops, take the boot lid off and on goes the wagon end. Softop for sundays.
The top back corner of the wagon section reeks old Valiant AP series, good tie to the 60's, also a bit of rambler in the shape.
Very interesting.
