Just Bought a 65 Barracuda that sat for over 20yrs.

I’d check the oil, throw a battery in it, squirt some fuel down its yap and twist the old ignition stick. You might be surprised. Ask the lady why they parked it, there could be some good info there. I bought my first dart because the previous owner parked it when the power steering pump wouldn’t work. I put fluid in it and drove it home.
