The Yesterland thread on "The Mouse" (Grumman G-159 Serial 121) parked at Disney Studios mentions that they retired Walt's Gulfstream I in 1992 and parked it on the Tour rout in 1993, and the interior is stripped out.
Can't be all that stripped out, because on a whim I pulled the records online - they renewed the Certificate of Airworthiness on 5/13/1988 and it's valid through 8/31/2014...
FAA Registry - Aircraft - N-Number Inquiry
The Airworthiness date is listed as 12/6/1963, so if they bought it in "early 1964" it was most likely brand new.
And you can fly a plane with the passenger area interior removed, all you really need is the Pilot and Copilot seats, and a floor to get in and out. Taking out the interior would reduce the chance of hidden water leaks and corrosion if they can see where the water is getting in. And simplify those periodic Airworthiness inspections.
It costs $10 to pull the full current records file on the plane on a CD-ROM, I'm almost tempted. Might be less on paper, but at 10c a page could also be a whole lot more.
Am I interpreting this wrong? Looks to me like (to use Automotive terms) they're "paying the Tags and getting it Smogged every year..." even though it's on static display.
