To buy or not to buy, that is the ?

Hello, my first post been lurking for a month or so. There is a v20 in my neck of the woods just put up for sale, its an '81 with various nicks and dings on the hull and keel. Transom seems solid, floor a little spongy beneath the captain and mate chairs, cuddy is trashed, will need to pull and toss everything in there. The engine is an '80 evinrude sport 200HP, guy says it runs, I have removed the cowling and the plugs are new, fuel line has been re-worked, overall lots of rusted bolts. The central large deck hold is a bit wet, cuddy door is missing so I am thinking that rain is draining through there. Boat is located in Biloxi, MS but this guy says boat has no "katrina damage". He is asking $3200, does that sound like a good deal? Thanks for any input...makoshark
