This is the side view control drawing for the Kenner Ecto-1. I've done my best to create a cleaned up, high resolution version of the available image. This didn't match the final product, and includes some unused ideas.

For fun, here's what it looks like without the cutaways and notes

Might as well show a few alternate versions while I'm at it, here it is without the tubes

And here it is with the fin as part of the door, which you can see if some of The Real Ghostbusters and Kenner concept art

You can see how closely this control drawing matches the hard copy of the prototype Ecto-1. This is the only picture I've ever seen of it. I flipped it horizontally to match the control drawing (and flipped the logo so it would be right from this view) for comparison. (The gunner seat is incorrect due to the horizontal flip, the guns would switch positions)

And finally, here is what it looks like with color. I used The Real Ghostbusters Ecto-1 color sheet as well as some of the Kenner Ecto-1 concept art to make a best guess at the roof rack color.
