Jim,
Let see:
In those three major defficiences you have:
Replace tanks $20K
Rebuild Engines $18K
Blister job $12K
Subtotal $50K
Now do not forget other items, they are all 27 years old. They will fail (tranny, cutlass bearings, alternators, etc.),
what about refinish the deck, rotten wood, etc.
So, if boat this vintage in great condition is worth let say $160K - 50K for repairs=$110K, other repairs need to be estimated at 25% value then it is about another $25K.
I would consider this only if price would be around $85K.
I have not included price of your time and frustration in dealing with boat yards.
No, I do not own GB42, but I have spent 10 years rebuilding my previous boat (Valiant 40) and I would not buy a boat that need a lot of work again.
Good luck,
