Does it run? My guess is no, most likely because the gasoline has long since gone bad.
It may cost some money just to get the engine running, not to mention tires, belts, brakes, etc. You could easily spend more than the car is worth. I’m not aware of any pent up demand for 1985 Delta 88s.
I think I’d auction it as is and take whatever I could get. It won’t be much. Good luck.
