Does any one have an ecto-1 made out of legos?
Yes, someone did made one. It’s not the full size version though or least I don’t think it is. I am sure someone will know the link to it.

NO EFFING WAY!!! i was there a few years ago. there is a place where you can watch the designer build and they had the sp man there. i asked them if i could take a pic of it and they said no and then moved itout of site.
