In the course of making Regeneration, I made a number of sketches and diagrams to help me plan out and describe various things in the story.
This is one of the better things I drew; my original vision for the Ecto-2. Much like the Ecto-1, it was meant to be built from a Cadillac, namely a 2016 Escalade. I later realised how common these cars are in the US so I changed the story so the model is never defined. It didn't really carry the spirit (no pun intended) of the Ecto-1 to have the Ecto-2 to be made from such a common vehicle.
The dome-like device on its roof was supposed to be a larger version of Hiroko's PKE lure device. This was going to be a key element to the plot at one point before the finale of the story was altered.
