With all due respect, I don't think you are focusing enough on the current marketplace. The data in the thread you referenced is over a month old, and has a one to two month lag time built in. Your statement about there being no BWV ROFR in January and February is incorrect. If you look at the boards you will see that there has been a frenzy of ROFR activity at BWV, with very few contracts passing.
The resale market is significantly different from what has existed for the past year, and the changes have happened quickly. Supply at many resorts is at a 12 month low, there are more stripped contracts listed now than at any time in the past year, and ROFR hysteria has people bidding $3-5 ABOVE asking price which is leading to an escalation in prices. Add on top of that the fact that ROFR activity is the highest it's been in years and I stand by my statement that this is not a good time to buy. That being said, I still feel that buying resale is better than buying direct, and to your point the savings are still there. Just know that you're not going to get anywhere near as good a deal as you would have six months ago.
I don't think you'll get as good a deal as you would have six months ago (or a year ago) until the market crashes again. Contract life will go down, which will bring down prices - but for years remaining, the last few years were a perfect storm for resale buyers.
1) Disney didn't choose to invest the cash they had on ROFR. Like most of corporate America, they were really hesitant to tie up any money in capital, which is what buying contracts is.
2) A lot of people discovered that with the downturn in the economy,
DVC didn't fit their budget and had to sell, creating more supply than before.
3) But less demand, because people with jobs weren't certain they'd keep them, real income declined as people didn't get raises (but park ticket costs continued to go up), and buying a timeshare, even for those in secure jobs, seemed foolish to a lot of people.
4) Disney had a lot of supply on sold out resort contracts simply through foreclosure. People walked away from their contracts.
Now, we are getting a lift to the economy. Disney feels they can invest in capital again - they don't have a lot of foreclosure inventory. The people who couldn't afford DVC have been washed out - most of the people left are pretty secure except for "ordinary" life changes. And people are starting to buy things again.
There have been better times to buy resale, including six months ago. But now is probably better than six months from now. Within the next year it will likely restabalize - probably where it was before 2008 - where you could save a little money going resale, but not a lot.
