I paid $3k for my '69 Deluxe - its a refin, but '69 was a desirable year (one piece body, trans tenon). Your '82 would be worth around $2-2.5k here in the USA. Sounds like you have a good deal going on it there.
Got any pix handy of your '53 GT???
Edit - if its a '72 Deluxe (looks like you have a typo in your post) in original condition, then you may get about $3-3.5k for it in very nice original condition here - sorry for the confusion).
