advert might be right thats not buckled it dented hard to tell from pictures
If its buckled its got a dent as below ie flat spot bent inwards or
i would bet 80% of 350z wheels would be similar to yours hence why all wheels end up with weights as the wheels do naturally deform on the road , only way around it is buy a new one, also the two measure tape pictures might be the angle taken from but looks like the tapes held at different angles which will make it more different than it is
take it to a garage and see how many weights it would take to run true
can you get a picture from infront and behind the face like the image above
