I'm definitely excited to build one to fill the time line and have things come together a little bit better! The Ecto-1A didn't get enough screen time in my opinion so this will be a nice transition for it!
I think the way they work around it is that althought in the ghostbusters lore the second movie takes place, the ecto 1A never exsited, they just had the og. BUT i cant wait to see what you come up with
Nice! Love your ecto 1 projects. I think you should do one more which was the black version as seen in the beginning of Ghostbusters I without anything.
There are two other versions you could do, the 2009 video game version (1B) which is mostly a mix of 1 and 2 and the black and grey ecto that ray buys. Although that would be hard to make.
