I agree the gxp is a little faster but its still a v8 and they do like tk eat gas. I have a 98 gtp and they are pretty quick and not too bad on gas. I live being that four door gtp that can whoop on those ricer kids who think they are fast. All in all is say get yourself the gtp good on gas pretty quick and when/if u decided to start nodding the gtp is a better bet plus they pretty insane if u mod them the right way.
