Its a great car if you don't mind the non-stock color. You will definitely have a barrel of fun in it if you haven't already driven it. This was the love of my life and I would still have it had it not been totaled. It had new stock paint, new hood sticker, NOS interior. Mine had the carburator which was lots of trouble.
I had an '82 Firebird and it was not a good car. 1 transmission, 2 rear ends, electrical, stuck power windows, broken lock button on shifter, plastic that became brittle (and I live in California), so I wouldn't recommend an '82 of any sort.
You'll have a barrel of fun in that convertible. Have you thought of just keeping it? You'd just be in both worlds.
