If it's the right model for your needs, you could view this potential purchase dispassionately as: buying a new engine, installed, and getting the rest of the boat for free.
Still likely needing your labor as much as your money. IIRC the major concern in this model is the starboard chainplate connection to the bulkhead. Nothing wrong with the design, just a place where water will penetrate down and cause rot
IF ignored by a succession of prior owners. Wet coring in a deck is another place where Preventative Maintenance easily *prevents* a labor-intensive problem after 20 or more years, in
any boat. I am presently in the middle of re-bedding all of our deck fittings (our coring is dry) and it's tedious work, altho pretty low tech. Even an amateur like me can learn the steps.
Do you have access to photos of the chainplates inside? Has the deck been sounded and 'read' with a moisture meter?

Owning a sailboat should not be confused with "investing" altho the non-monetary rewards can be life changing.... !
