The Ghostbusters' Ecto 1

I started working on a story idea for a possible Ghostbusters 3 a while back with a friend just for fun.  It was turning in to something really great and epic but then we heard that they're actually moving forward with a real Ghostbusters 3 movie so...  oh well... the idea was great while it lasted.

Here's the design I did for the "future" Ecto 1.  Pretty mean huh.
