The other thing to consider here is the mission profile.... i.e. what do you want to do with it? My guess (and that's all it is) is that you may steal the purchase price but would require so much more to actually get it airworthy and usable for any length of time.
There are several (newer) aircraft that will do the same or almost the same as that frame and cost less than that top end to purchase and much less to maintain.
