Specifically, they were made in Australia - - on it's west coast, Perth, a whole continent away from the closer-to-the-US east coast (Sydney). They only made 336 of them. Only a handful were exported out of the country, so it's rare to begin with and rarer still to see one here. I don't think I've ever seen one up for sale before, though I don't watch all the auctions. Is it worth that? I really like the game, and I know Classics, but I wouldn't spend more than $2K on one, and that would have to be in top condition. But someone_ was willing to pay that, and someone else was willing to pay almost as much and drive the price up. I hope they're happy with it.
