You have to give us the exact model ie work VS ***. Most ppl will tell u , yes they would have been worth 1k per wheels brand new years ago but with the market nowadays, they depreciate a lot too especially 17s. If it is a popular model and in immaculate condition you might be able to fetch 2k if you are lucky....If u had a set of immaculate TE37s in 17 then I'd say you're almost guaranteed 2k at least...
have a look around the classifieds and also traders getting wheels in from japan yahoo auctions and you will get a better idea. fwiw, 18s seem to hold their value more nowadays as well...
