I do investigations for a living and have recently been doing more of these for people. I have located the vehicle for you if you are interested our fee is $250.
If you have the old tag number it's possible. If you could get the vin that would help.Dang! I kinda want to find my dads 84 vette now! (Piece of shit, I know, but I was 5 years old and that thing was I rocket ship in my mind!)
Could you find it without a vin?
