This 1986 GMC G30 was apparently used on Miami Vice and Nash Bridges and later tricked out by the American Institute of Parapsychology to investigate hauntings. The current owner is auctioning it on eBay with a starting bid of $3,000.
From the auction listing:
Comes with working pan/tilt mounted on roof (camera removed), deep cycle battery bank-(all hold full charge), a 250gig 4 channel DVR which also records 4 channel audio and acts as a quad.You could record audio and video remotely for a month. Huge power inverter to run everything you need on 120v AC. Like new Samsung 17″ Flat Screen monitor. 2 smaller swivel LCD Monitors. Pan Tilt Controller, dash mount flip out LCD monitor and rear mount infrared camera for backing up easily. I also have the 20 watt low frequency tx/rx set which is like new,used with the van and already mounted antenna. You can recieve and record clear audio and video for many miles with this setup. Integrated sound system in the back along with a video effects board. All equipment works very well. Four swing out chairs and a practical work area in the back. Even has a huge xray flourescent light table viewer mounted to wall. Windows are mirror tinted. Has a very solid tow bar section for towing another vehicle(see pic). Van has been in everything from childrens books on ghosts to above mentioned tv shows…
Not a show vehicle but absolutly awesome potential with a huge number of uses: Surveillance/Spy, Parapsychology,Police, Military,Camping, Ghost Hunting, etc.
