I read a bit about Acro shows a while back, and one of the things that have stuck with me is the "Clipped Wing" aircraft that were modified for performances. Part of me thinks it would be cool to own one and keep it flying as a historic piece. I presume most of these were modified in the "Experimental Exhibition".

What would be involved in buying, maintaining and operating a second hand "Experimental Exhibition" category aircraft? How would it differ from an Amateur-Built or Standard Category?
