I got my first one in Oct 05. Only options it had was AC (a must have in AZ) and the computer info center.
Eventually I installed the Fujita intake, Magnaflow catback and a reflashed ECM. This past winter I got a custom trailer from Adventure Sports Products. I loved that car but I had close to 70K on it and the dealer was making screaming deals on the 08s. So 2 weeks ago I traded it in on a GXP with all the bells and whistles. Immediately I installed the GM intake and exhaust and this past weekend the GM turbo upgrade. Nice!
