Just depends on what you personally want, your budget, preferences, etc. If you think gas price is going to be a concern, then you have to consider that even the GT might be too much for ya. Afterall, gas prices are high, and will only continue to go higher and higher. Especially since these cars "recommend" Premium to get the most power out of them anyways.
But if you
really want a G8, then you could almost consider the GT a great compromise between the V6 and GXP. And then you can use that extra $$$ you saved on gas.
