NewbieG8GT

I am looking into buying a G8 GT in the next couple of months, I wanted to join this forum specifically for the threads, but I am also looking to see what I can do to the car when I eventually pick one up. I am new to the "muscle car" scene, I've been to a lot of Car meets in Houston over the last 8 years. My brother had a G8, a Focus ST and a Mustang. I loved his G8 it was modified so I want to get one and modify it as well.
