Behold the power of google. The 1977 Toronado XSR story
ASC had developed the power T-top system and wanted to show it off (and of course, market it). So, after some discussion, a Firethorn 1977 Toronado Brougham coupe, VIN 3 57M 000055, was pulled off the Oldsmobile assembly line and sent to ASC for the conversion, which would include installation of the wraparound backlight and the power T-top system.
Oldsmobile apparently decided that the T-top part of the conversion would be too expensive, going instead with a moonroof. The XSR prototype was initially ordered to be destroyed. ASC, however, took the position that they had a vested interest in the car (their $5000 prototype power T-top system!), and they felt that the concept was marketable, so the XSR prototype was sold to ASC through an Olds dealer in Flint, Michigan. ASC owned the car for four years, showing it at specialty shows and promoting its power T-top system (which evidently was a commercial flop... ever seen a car that has it?), putting 19000 miles on the car during that time. At that point the car was sold to a used car dealer in Ohio. Someone at the used car dealer apparently liked the XSR because when the car was sold to a Louisiana collector a year or two later, it had over 40,000 miles on it. The Louisiana collector got in trouble with the Bureau of Eternal Revenue somewhere along the line and the car was impounded (along with other assets). Apparently it was stored outside in a swampy area for some time where it evidently sustained considerable rust damage. This was, in part, due to the fact that the drains for the T-top system were never "plumbed" through the body cavities and to the outside of the car, since it was a prototype and not expected to see actual service as daily transportation. The car was eventually reclaimed by the Louisiana collector and then sold to another car collector near Winchester, VA about ninety miles from Washington DC.
From there, the car is restored.
