The car is a Buick GN and my friend was down in springfield IL over the weekend and said he could see it from the Highway Interstate 55 just past the D.M.V by a lake or a big pond on top of a hill parked in the yard or driveway next to a house with a yellow for sale sign in it.Any help would be great I was just wanting to find out what year it was and how much they were asking.I was told by my friend that the car has been out there for a long time.....Thanks for any help
