I got as far as the last section of the tail, but I'm calling it quits on this project.
I just don't feel confident enough to drive with this.
I am no engineer, and the risk is too great for causing an accident if something falls off while driving.
I did have some things that went right though, and someone else may be able to benefit from this experiment.
The entire tail is easily removed, and can be stored in a walk in closet in less than 30 minutes.
It leaves no drill holes on the outside of the car.
In city driving, the tail retracts. The full length of entire car with the tail retracted is slightly shorter than a Toyota Camry.
I also had full functionality of the hatch and glass.
This is a video that shows the extension and retraction of the tail from the driver's seat.
It is cable operated.
The last part of the tail is not installed at this point, and the segments are crooked here -
It functions the same with the last section and lights installed.
If you look closely, you can see the lst section of drawer slides.

The car is bare metal with an aircraft theme. Obviously, it has started to rust.
I planned to fix this later.
By using Gibb's lube and a spray sealer, the metal will actually stay pretty rust free.
There is a bare metal car that runs on the SALT flats using this technique, and it seems to work great.
