That's the asking price. You can say that he has made a circumnavigation but on the other end is a boat with less than three years. They have a lot of equipment on the boat from solar panels to an hidrogenerator and I don't know if a watermaker, but yes I believe they will not sell for that price. They have plenty of sails but not a furler. They are good sailors and like to use sails on a tuff luff but that for a solo sailor would not work. I believe they will sale for a lot less.
They have a lot of sails that also did a circumnavigation... Same for the equipment. I'd say 80.000-90.000€ is a realistic price.
