X-Star or Supra 21V

Ok heres the deal, I am looking at purchasing either a new 2007 Supra 21V or a 2005 left over demo X-Star. Both boats will have new finance options and full factory warranty. And both will be very similar in specs and very close in price. I think both boats are great and will by far out perform my ability. So here is what I am having a hard time with. Which boat will depreciate faster or should I say lose me more money when I decide to get a different boat in 2-3 years. The mastercraft has already taken its initial hit, but it is 2 years older to so maybe it will be depreciating faster. Any thoughts are appreciated. Thanks!
