Spare parts are probably attainable (there's a reason retired aircraft are mothballed rather than scrapped), and the major companies that the built the engines, etc, are still around.
Out of 500 or built ~60 are still in service. Getting parts as a civilian operator might be touchy though. It's probably being sold more as a museum piece.
In terms of doing a restoration Russian stuff is usually pretty viable since mechnically they're fairly straightfoward and rugged, and not much in the way of computers or microelectronics of any kind. Even with all that said, it would probably be a $10M+ (quite possibly +++) to get it airworthy again, and even if you did it would be very expensive. Fuel burn on those things is about 2000 gph, and Jet-A is currently ~$6/gal, so you're looking at $12k/hr just in fuel expenses. Maintenance will probably at least double that hourly figure.
