I will vouch for John.
I bought his old set of wheels before this set, American Racing CL205's. They were in better shape than described. He's a true gentleman and somebody you can trust 100%. If he's saying they have less than 500 miles, I would believe that.
Heck, he even polished and cleaned the wheels I bought off him before I got them. I was already sold on them, but he wanted to make sure I was happy.
