IMA Z06, it is mailed to "recent" purchasers of new Corvettes for up to 3 years gratis. After that you have to pay the subscription fee. However, I know I've seen it in book stores on magazine newstands. If any of you have bought a new Z06, you should
automatically be getting Corvette Quarterly in the mail, however sometimes you have to call the # Zippy mentioned to request it.
