That is a Comp G. I can see the little rectangle Comp G badge in the middle of the drivers door. Besides, those are the optional Comp-G wheels on the car as well, red calipers, etc, that are only available on the Comp.

But keep in mind tho with an 04, you dont have the digital dual climate control (didnt show up till 05) and the 04's still had the plastic LIM gaskets. I see that car has only 40 some thousand, youd be good for a while anyways...
