I almost never have passengers other than my girlfriend, and she has no desire for babies for a while yet. And she encouraged me to get the coupe.
Thanks for the info and the link! Will be very pricey, but hey, pricey car, eh?
So I pulled the trigger today, got the G37xs with Navigation, Premium and Sport packages, spoiler, splash guards, illuminated kick plates... and the cargo net/emergency kit/carpeted trunk mat. Wouldn't have picked the latter but it was already in the car, and I got the whole thing for $44,232, almost $700 below dealer invoice (per Consumer Reports). Cashed in on the last day of the 1.9% financing offer, and they gave me a great no-haggle trade-in on my 14 year-old truck. I'm very excited! GF is ready to take a ride into the mountains tomorrow.

Will be hanging out here a LOT, I think.

Thanks for all the advice everybody, great to see an active community!
