Correct no offset specs, no finish, weight, or are they 1 peice 2 peice 3 peice wheels? No visible curb rash doesn't mean there isn't curb rash under the plastidip. And offering up Dp's (which you asked for) is not low balling it's a starting point. you should have countered with DP's + cash of some sort of number. Give us buyers an idea of what you are looking for or at least a general price. The $400 wheels I got from tirerack are Breytons, a pretty reputable brand and I know the weight, offset and everything.
I asked questions to try and find what these wheels might be worth, I was willing to put cash on top but didn't know where to even start or if you were even interested in my DP's your not so no big deal GLWS.
