Reading the original linked to page I think the money would include extending the museum, expensive enough in itself I would imagine!
I have looked at this exhibit a few times over the years (last time 2015), it is tucked away in part of this fine museum/gallery, the present display area can hardly be described as eye catching.
My take on this is:- if money is spent on making the plane look top notch and displayed in a new glass fronted gallery area then (hopefully) more visitors will be attracted to the museum itself via a “come and see our Spitfire effect”.
As to a flying restoration – surely it is hardly a case of just restore and fly? The ongoing costs of doing that would probably be horrendous, plus as Brian points out the exhibit would no longer be in the museum.
