Water will be your biggest enemy. Be sure to get a Surveyer that at least claims to be proficient with a moisture meter. Water under the teak in the cored fiberglass is a priority if the teak is screwed down. If it’s got antennas on the sides of the flybridge that is another source for water to find it’s way into the sides of the flybridge. In the long run they are rock solid boats and you will love it. Congratulations and good luck with your new boat.
