I suspect that in the case of Alembic, a Series II will do all the talking to the new buyer that'll be necessary. That being said, look what Paul did to his 4001, or what John did to his Rolls-Royce, so yeah, there's dummies out there. Every now and again they stumble into something nice - maybe even "above their station", in a way - and proceed to trash it. Sadly, once you get the money, it's out of your hands.
Brings up an interesting question: let's assume nobody ever heard of Stanley, he's not a recording star or composer, he's just a everyday clubbing stiff from Philadelphia who plays good, you know, like Stanley. Knowing how he plays, would you be eager to buy one of his Series IIs when he retires ? My answer is no, not really.
