I would call a salvage yard and ask them. I would not expect they would sell for to much, especially being 7 years old unless they were in mint condition.
1 of my OEM wheels was pretty nicked up,the others were great. I took them into a recycler along with a bunch of other metal and got about 100.00 for the load. I tried to sell them here but shipping pretty much negates the value of buying them used unless they are local.
Just by the new wheels. Keep the old ones and maybe you can put them back when you sell the vehicle if you buy one with the same bolt pattern.
or just put them in the paper for best offer.
