For the price and the condition and amenities in the Gram I think it looks like a nice boat. What kind of condition are the sails in? As far as a stove goes, we used a rail mount bbq to do everything for years and even now that I have a boat with a stove I still do most of my cooking on the bbq. The size of the boat, even without roller furling is very manageable.
Also it is a buyers market so figure you can knock em down under that asking price and that is just more money for you to modify how you please.
