The side. You can see something inside the car, right?
The interior. Not much of space, as you can see.
The top. I'm not really glad with this part, since I don't have all the parts in the needed colours.
The Ecto-1 have not only appeared in movies, but also in The Real Ghostbusters.
Here it goes...
What is it?...
Fold down the wings...
Here we have the Ecto-2, their alternative flying vehicle! I know isn't accurate to the original, but I have no idea of how they could keep this thing inside their car with such small space!
The tow cable.
Another extra: The Ecto-Copter. I know, they already have a flying vehicle, but I could not resist. :D
Really nicely done, I like mainly the flying custom motorcycle.
Good luck to the contest :)
(I don't rate your creation now because, once I'm the organizer of the contest I can't rate it before it's over, but I'll rate later)
