I have several comments on this thread.
The first is, as others have mentioned, this is the ultimate DVC fan club so I wouldn't expect a whole flock of people saying they sold because DVC no longer met their needs. Obviously many have sold and are selling now, or there would not be any resale market.
The second point I would offer is that prospective buyers should answer one fundamental question before they proceed any further with a DVC purchase, or the purchase of any other timeshare. That question is: Is timeshare ownership the best solution for my family's vacation lodging needs?
There are many, many alternatives to timeshare ownership and many of them fit many families a lot better than anybody's timeshare. Before anyone purchases any timeshare, they'd be smart to consider all of those options and answer the question above -- is this the BEST way for my family?
The other point is that I think every prospective buyer should consider your thoughtful question -- yes, this will be great right now, but what about later?
Times change, interests change, economic or domestic pressures dictate life changes -- the list of things which might make someone want to get OUT of any timeshare is probably endless. Before someone enters into a 30-50 year financial commitment for annual fees, a long hard look at the suitability of the purchase way down the road is in order, IMHO.
I also think prospective buyers should consider an exit plan. If you decide to sell - for whatever reason - how will that picture look?
If the purchase was made direct at today's prices, that picture will be ugly. If the purchase is made resale at today's prices it will be less ugly, but still not pretty. In either case, the sales price is likely to be significantly lower than the initial purchase price.
