I see it that way too, Chris. Buying brand new with full warranties certainly adds some value, but the minute you take delivery, it is still a 2007 used boat, with low hours and some warranty. That may still make it one of the more desireable boats, if you were going to sell it again, but it's still being seen as another used '07.
Check the sites that show what 'used 07's or '08's actually sold for (as opposed to asking prices), and then go from there. If you don't want to drop that kind of money for a new boat, there are some beautiful used ones, reasonable hours, and decent electronics, for way less.
