Low mileage garage kept 1967 Eldorado

Car has been in storage for many years. I have recently cleaned gas tank and had it lined. Also replaced drive axles, water pump, and tires. Car runs and drives but does have a slight miss. I think it is vacuume related. Interior is in excellent condition and body is very straight with even gaps. The Under carnage was sprayed at dealership with undercoating. Has older repaint with minor issues. With a little work would make a great driver. Or great start for high end restoration!
