Listing says "Skylark" but if orig. paint as stated it's a GS w/a Stage 1 https://www.ebay.com/itm/144457029759?hash=item21a24f587f:g:84YAAOSw~59iI6h1
I don't remember that one. Odd he wouldn't list it as a GS. Looks like a GSX steering wheel & Wheel Vintiques wheels.
If it sells for the asking price or even close, then I had mine way underpriced when I offered it up for sale.
Same car, loved it then love it even more now. I am trying to find the v8 post on it, but it must have been in the bench section and not leads... it was a few pages long and if i remember right the car sold in the low-mid 20s. 71 is my favorite year GS. https://barnfinds.com/1971-buick-gs-stage-1-455/
