Wow Bill! You are very lucky to find your car still in one piece
I would try to buy it at auction if I were you. You've done so much to try to find the car and you finally found it. Why just let it get sold to someone else who will possibly trash and destroy the car with hard use?
Granted you just bought another mustang, I'm sure there would be a way you could get your car.
Did it still have all the lights? Or will the insurance company rip all of that out?
Glad the car was found
