~$100K is the going price for a HC38, a Tayana37 or the Baba/Tashiba versions for a 'quality' boat of the mid 80s vintage. You can go cheaper if you want a 'beater' but these boats are starting to show their age especially if the maintenance was ignored.
The teak is no problem if you use one of the modern long lasting coating systems: Honey Teak, Bristol, etc. Typical service life of Honey Teak is about 10 years with 'some' maintenance coats in between.
The REAL problem on these era boats is that their screwed-down teak decks are now becoming 'wet' and in needing of a $$$$$ replacement, and some have severe chainplate problems ---- all 'age' related.
Here's an example of very maintained Tayana 37: 1984 Tayana Cutter sailboat for sale in South Carolina
