As to value, unfortunately, they are not one of the more desirable wheels, so they won't be worth much. Someone may pick them up for winter beaters, or a cheap upgrade in size/style for a GM that came with even less desirable wheels. If he could get $200-$250 for the set, I'd take it and run.
Thanks for the input. Perhaps I'll buy them myself. I have the 16" crosslace rims, so these would allow for a brake size upgrade. I wasn't keen on touching them before because I believed they were 18", and didn't want a rim that big.
