An older gentleman that lived a few houses away had one of these when I was growing up. Had a 500ci in it and was supposed to be the last convertible Cadillac, it was pristine and very rarely got driven.
I remember one time I was doing lawn work for my dad and heard this super loud noise, one of brakes had seized up and my neighbor was driving it into our court spinning the back wheel(s) ( I am pretty sure it was one wheel, but it was int eh 80's so I don't really remember).
This color with a white top and white leather (vinyl?). The thing was huge.
