There's a couple 'pie cars' (diners) that would deserve investigation, and a couple of generator / genset cars that are really state of the art.
Most of the other cars have been heavily modified into rolling apartment buildings or railroad Winnebagos. But they did take care of the equipment mechanically, didn't want on-the-road breakdowns. If you want a solid, interchangeable Budd shell, that you can bulldoze out and make into a lounge or table car, it has some potential. An all-stainless Budd shell in interchangeable condition converted to all-electric is most certainly not scrap.
What's also interesting is the 10-day window for bids when some of these cars are possibly out in the field. They'll only get scrap prices that way. You may see somebody familiar with the cars place bids, but most buyers won't be able to get their hands around it fast enough. I'm wondering if they have creditors demanding payment pushing that deadline.
