https://martinsburg.craigslist.org/cto/d/kearneysville-very-rare-buick-suncoupe/6848340658.html Been listed for a while, asking $12,500, that's all I know: "VERY RARE Buick SUNCOUPE - Skylark - 1972. You may never see another car like this. 1972 was the ONLY year Buick Produced the Suncoupe. And, estimates are, there was only 1600 produced. This one has the Stage One, GS 350 engine. Also, the Rare GSX Ram Air Hood with the Outside Tach. Runs and drives, very solid car for year. I was going to ad the fin and repaint to make a GSX Tribute car, but no time."
