Considering the price of a new SR Q-16, if it's structurally sound, I don't think that's a bad price. You didn't say, but I'm assuming its Kevlar?
We have a few people of the Q who have multiple canoes and often recommend people look for used ones via the on-line marketplaces. They know more than I about it.
I rent a Q-16 Kevlar same one year after year and it's easily that old.
If you get it, check out this site. They show how you can easily restore the hull to like new condition with a new coat of varnish and a little elbow grease.
