Have a 37 of same year. Only two exterior weak points are stanchions - particularly the bases if they are fabricated Stainless like mine, and hatches. The original Rutgerson coachroof hatches leaked badly but should have been replaced under warranty. The windows can also leak if not closed fully and the trim strips inside fall off and difficult to get replacements. Cabin lights are fragile if used heavily, but seem OK on private boats. Original cookers are rubbish and the gas installation does not meet current standards. If you have a Lofrans windlass check that the base is not corroded where it sits on the rubber pad.
