It's not new old stock, but a used tank in very nice condition. The seller first describes it as "perfect" but then goes on to note that the warning stickers are yellowed, and the photos show a few other minor blems as well. My dictionary defines "perfect" as "without flaw," but such is the world of online selling. The opening bid is $2500 and shipping listed at $125 (!).
I suspect the seller is a little optimistic on his valuation here, along with his other RC30 auction item, a headlight fairing listed at $1900 with the same shipping quote. Happily, to help potential bidders rationalize the cost of his parts, our seller includes this tactless explanation: "They are now rare as rocking' horse poo. Thats why you have to pay for big bucks for it." (sic)
Good luck with the sale.
Update: Both items unsold.
