Wow, that looks amazing! I'd love to have one, but it isn't very practical for living in Colorado or a family man.
Well you have a year to talk the Mrs. into it
In my opinion, the nostalgia and pure adrenaline rush on the weekend is worth it. Let's face it, it's more of a luxury car, in the sense that it's not a daily driver. More of a weekend cruiser, sometimes one day a week. Then again I have no wife or kids so maybe my reasoning is different than yours.
So drive the Dream Machine (aka: Van / SUV) during the week with the kids, and the Z06 on the weekends.
