I still have my 72 Supreme. I sold all of my rare Oldsmobiles and kept that. I’ve had it forever. The Supremes are much like the Buicks where the filler panel and back window can have rot and cause a headache. The S/442 bodystyle is a lot more forgiving in that area because there is no filler panel. The glass goes right to the trunk lid.
A friend had a black 70 cutlass in high school, 455 with the white stripe around the wheel wells. My buddy thought his new 5.0 mustang was fast until that cutlass showed him it wasn’t as fast as he thought.
