I just think that having the added comfort of the AWD would be good if we start a family in the next year or so.
I hear ya on the family security thing. I've got an 11 year old and a 7 year old. I can't tell you what to choose, it will all depend on your level of comfort with RWD and snow. I'd never dream of navigating our winters up here with an F-body (although I've been in a couple of F-cars outfitted with snow tires even during a bad storm at one point, but they are just not balanced enough).
We cut our teeth up here back when they were all RWD and snow tires went on the back only (with summers up front!). So it was sort of a homecoming back in '03 when I went to using 2003 Mercury Marauders as winter cars after over a decade with 80s and 90s Honda products (Civics and an Integra GS) which themselves replaced a mid 80s Pontiac Parisienne (the last time I did the rear snow/ front summer thing). That move back to RWD didn't even make me flinch (Michelin Arctic-Alpines) and the same feeling of security carried over to my Charger in 2006 (with Blizzaks).
We got a foot-and-half of snow within 24 hours on Dec 27, and the car pulled itself out with no effort, and I honestly can't think of where AWD would get me better stability other than when the wheels are turned and I'm trying to accelerate on ice or out of deep snow. In 100 000 miles (most of them winter, due to my summer cars), I haven't met a snow storm that's given me any worry. I discounted the AWD because of the additional weight (and my own personal opinion on the wheel offset and suspension height). But it's a personal choice, as to what you're comfortable with given your local conditions.
I think what made me get over my fear was when I went a couple of winters with a naturally-low '92 Integra GS 5-speed with decent snow tires... I wouldn't expect any less from a Honda product, given its Civic roots, but when I found myself navigating through unplowed parking lots with total ease, I figured there was something to decent snow tires.
Good luck with your search. Hope you end up with as good/fun/safe a car as I have been blessed with.
