Not to put you out or anything, but since you mentioned that you have paperwork, would you mind posting pics of it? The reason I ask is because my rims were stolen a few months ago, and I'm very skeptical of people from the NE selling these wheels, especially when they're obviously new to this message board and don't own a Z. I don't mean to be offensive, so please don't take it that way.
Here's my thread for your reference:
370z sport wheels stolen!!! Help!
Thanks.
