Don't see them in classified section. I've always wondered why these wheels aren't more popular for winter use. I suspect it's because owners price them too high, driving prospective buyers into the aftermarket. What are you asking for yours?
$480 is probably a reasonable price, but if I were you (and I may be one of these days if I ever decide to replace my 17s) I'd put them on eBay, start with a low minimum (say $30/wheel) and let the market take them to wherever it will take them. After all, they're just taking up space in your garage and they'll never be worth any more than they are now. Just my two cents.
Just an FYI. I bought OEM 17" wheels on eBay to mount my snows. I bought them in Dec 2013. I paid $499.95 for the wheels and $79.95 for shipping via FedEx. I was very happy with my purchase. I think you have them priced fairly.
