This model was heavily inspired by the 2014 original eight-studs wide Ghostbusters Ecto-1 (set 21108) and a convertible MOD of that set I found on Rebrickable. I've been kicking this model around in my head since early September in several colors, (black, blue, dark gray, and red were among those considered) but green is the one I finally settled on.
Instead of a late-50's Cadillac Miller-Meteor ambulance, it's now based on the (very similar) '59 Cadillac Eldorado. In the changeover, I added a hardtop (removable) roof, mirrors, and 1/2-stud offset side-by-side seating for two (with a third seat in the back row). I also changed around the wheels.
I thought about putting a spare tire back here, but it proved to look stupid no matter what I did, so I left it off.
The roof and rear windscreen are only connected by a few studs, making them removable. The car easily seats three figures total.
Here is the original set 21108 I was inspired by, Ghostbuster Ecto-1 from 2014.
Thoughts?
