So ladies... final choices below. I added potential layouts with objects to get an idea of space. Doesn't mean you need to follow this.
I tweaked the 5 wide car to push the doors closer to the edge in Option A which gives an extra compartment. I'm assuming you are OK with a 2-wide.
Please rank the choices... we'll go with the majority and move on. It will be great if any others thinking of participating could vote as well :smile:
Edit: Option D is a 5-wide version of Option C - windows will be fixed for symmetry in both versions.
