The shape of those sills looks... interesting.

With regard to the white RS replica above that remained unsold, it was quite common for targas to be converted to coupes for racing in the early 90s as they had extra body stiffening. Not many race cars from the Porsche Club Championship in the early 90s actually survived to this day - too many major accidents and repair cost too expensive. This car looks unusual with SC style dashboard and door panels and the later fuse board looks out of place.
