Cool! 2003z(Mike) and I are both near MikeKZ in the southern Gwinnett county area. Now is a good time to buy as house values are stating to jump up pretty good...
I know of MANY hybrid Zs around home that aren't on HBZ.
There is at least one RB20DET powered Z, a couple SBC powered Zs, and a couple unmodified Zs that are daily drivers... There are at least a 3 other high performance L6 guys beside myself too.
All that on the East and Northeast sides.
