More improvements of the design

Here is my latest sketch.
It shows the convertible top version with the childs backseat and luggage space behind.

 

 

 

As shown below, the luggage space of the convertible is around 90litre/3,17cubic feet, the space for the childs has twice the volume.

 The translucent bodys represents the space provided for childs and grocery.

With a disassembled backseat the space in the rear is around 270litre/10 cubic feet.
 

 

The same partition of the space behind is also possible with the formerly shown Kamm tail.
