I drive the Comp G and the wife drives the GXP. We bought the Comp in 05 new and i recently traded my WRX for the GXP a few months ago. I really love both cars. The GXP stock for stock is a smoother and faster car but i love that supercharger whine. The GXP only has 30,xxx on it so its gonna be stock for now. I am in the process of upgrading the other and so far added some Autolite 605's and a 180 stat. More to come!
