ECTO-1C
The ECTO-1C is the West Australian Ghostbusters' primary mode of transportation.  It is capable of carrying seven people or a smaller team with full equipment (proton packs, traps, PKE meters and other assorted gear).  

The ECTO-1C started off as a 2014 Kia Grand Carnival and saw use as a hire vehicle before being purchased, repurposed, and dubbed the ECTO-1C.  

The ECTO is in a continuous state of upgrade as it is added to and modified to suit the needs of the West Australian Ghostbusters.
