A little off subject but I opened up a coach for lighting and saw that there is a hard inner window plastic that is covered by a semi transparent film on the car itself. So I cut away the hard white plastic on the roof that covers the windows, and put some people in crudely as you can just barely see in the windows. Now you could put clear plastic in and do a fully detailed interior which would be very neat but this just adds a little detail.
As original on the left, modified on the right. I was planning on painting the roofs black as it appears they are in the movie also.
