I would make a list of all the parts it needs, and how far you want to go in restoring it,you could spend 15-20k to make it a decent driver and over 30k to do it right.I break it down 5 ways. Interior cost, under hood cost, drive train cost, body and paint cost and exterior cost: wheels,tires, trim pieces, bumpers,grill work, side markers,rocker panels and so on.
