Wheels and tires seem to run in the range of $1200-$1500 on eBay before shipping. I ended up having to buy two sets in one seller fell off the face of the earth and both were in that price range. Not much of a CL wheels market around here, but I had seen a set of wheels and tires for $1300. Almost all of the listings claim to be extremely low mile take-offs, FWIW.
For just wheels, I had seen them on ebay in the $750-$900 range, mostly toward the high end of the range.
