Porsche 356A Beutler cab-ex-Grace Slick

I read about this convertible, the only open car out of six Beutler (Swiss carrozzeria) built cars, and how it was owned and used as a daily driver by singer Grace Slick of the Jefferson Airplane, when she lived in the SF bay area. I am wondering for historical purposes if anyone remembers seeing an ad for the car when she sold it or any of the other owners sold it before it reached its present state of restored perfection? I bet it was just an under $6000 car for a long time but would like to hear the price. By the way it doesn't look anything like a 356 Porsche and has a faux grille in front.
