In a cross compairison of the Ecto-1 by Polar Lights, and the Ecto-1a by Ertl, was in this months issue of “Modeler’s Resource”. The current issue, on sale now, features a breif mention of Ecto-135, as well as a little blurb about the Ghostbusters Prop Archive. If you are here after reading the magazine please let me know. The magazine has a great article about the cars, and how exact to the movies they are, as well as a good cross compairison. Most of the parts are actually pretty interchangable, and show forgotten details. Get the latest issue in Hobby stores, and on news stands everywhere
