You don't say what motors/drives are in the vessel, or where it is,In 93 sundancer was a good make, well built, solid boats, they were ahead of the designs of other makers and everyone else tried to copy, my advise is to get a marine survey of the boat, and then while you are on it check every spot you can get a look into, and it might help to get one of those mini cameras that mechanics use to look into engines, for the areas you cant get your head into, and if the owner won't allow this then walk away, also in the southern states look for sunken boat damage, hurricanes that flood and sink boats can do a lot of damage, that you just cant see, it's like buying a car thats been sitting at the bottom of a lake, and sometimes dealers buy cheap storm damaged boats ,ship them somewhere else clean them up and sell them as local area boats, and not disclose storm damage, so check where it was first sold and registered, and go on from there good luck Myles.
