I was looking at buying direct VGC in Oct 2010. Direct price was $120 but with incentives and some specials going on it would have brought the price down to $95 point (had a special on the last day we were at VGC where we got an extra $1 off....for some reason I remember that

). If we had pulled the trigger and financed the 350pts (did not as the economy was still shaky and didn't want to use our on hand cash) with 20% down. The price would have been $33250-$6650=$26600 out the door (no closing costs then). The interest the past 3 years at 10.5% would have been $7609($22). So about $117($95+$22) per point today.
Much cheaper than the $165
DVC direct price and in line with resale prices today. I would have gotten 4 years use of the contract also. Now this analysis would probably not work for every resort but in my case I would have been ahead by financing instead of buying direct at $130 now. Buying resale at $115 with closing would still cost more than buying and financing 3 years ago. YMMV
