This 1:8 scale Ghostbusters Ecto-1 partwork build-up is the most detailed model of its kind. It is based on scans of the actual screen-used Ectomobile that was recently restored by Cinema Vehicle Services. However, for a model that costs upwards of $1500 USD you would think it would be perfect, but you would be wrong. There are definitely some shortcomings you will find as you build it and they may or may not drive you crazy.

Luckily, there are communities of fans who, like myself, are passionate about the movie and the car.  Some of them have produced some amazing custom modifications (mods) you can add to your Ecto-1 model to give it more accuracy and detail.

Some mods are very affordable and others are quite expensive. It is totally up to you which ones to install. Every build is going to be slightly different no matter what, so do what you want!

On that note, here is a list of the mods I have chosen for my car. Details on and where to get each mod can be found on their individual pages.
