Good advice above!
I owned Wellcrafts for 20+ years, good boats but condition is everything.
One of my slip neighbors had a 3000 Martinique, very good layout.
A pre-purchase survey from an accredited marine surveyor can save a whole lot of potential issues.
I HIGHLY recommend you get one for a big boat.
