I still have a Tithonus vinyl soft top in Sand, with side windows, brand new in the box. PM me if you interested.
The coloured Tithonus tops are custom made by my local trimmer. All in mohair fabric, same as Mercedes Benz and Porsche uses on their convertables which is quite expensive. Price for the complete top is steep at rougly $ 3.5K a piece. We have now changed the design slightly so the side and rear windows can be fully removed instead of rolled up which added another $ 500 to the price. All stainless hardware, Tenax fasteners and marine quality zippers.
