We don't dig the minivans, either...hubby has always said he'd buy an old stretch limo before a minivan if we had more kids. hehe We have an Audi A4 wagon and it suits us perfectly. It is functional and sporty and very comfortable, and really is just a joy to drive imo - and our's came with a free scheduled maintenance package, so we've yet to spend an extra dime on that stuff.
Performance stuff: I get 30mpg or better. It's a 4 cylinder, but has a zippy turbo engine and can really move if need be. The Quattro all wheel drive feels really secure no matter how much snow we get. It has the tightest turning radius of any car I've ever driven and is reeaally maneuverable. That and its smaller size lets me turn around easily and park in spots that SUV drivers can't touch!
Kid stuff: I'm sure a lot of the minivan and SUV moms would say my 2 kids and their car seats look a bit cramped, but they're quite happy. I could see upgrading to the bigger A6 wagon when they get to be tall teenagers, but they're totally fine for now - and I like that they're close enough for me to reach out and hold a hand or offer a toy at a stop light.
Stuff stuff: The cargo area is plenty big enough to carry our (large) stroller, a big mess of groceries, and a couple of extra bags and blankets and whatnot. The back seats fold down to extend the cargo area if need be (we don't have a truck or SUV and have used the wagon to haul big things from time to time). Being a wagon, it doesn't have a lip into the trunk that a car would nor is it high off the ground like most SUV's - so it's easy to get big/heavy things in and out, and very easy to lay a baby down for a diaper change on a roadtrip.

Comfy stuff: Heated seats! Before I ever had them, I'd have laughed at the frivolity of such a thing, but now I don't think I'd willingly do without them in a cold climate.

And it is just comfy...long road trips are a breeze.
The downside is that they can be a bit pricey, and I doubt that I could do 3 car seats in the back. I can fit between my kids' 2 car seats, but 3 car seats would be pushing it for sure (although I think the current model is slightly bigger inside). The A6 would be better for more than 2. We ended up finding our's practically new on ebay motors and got a helluva deal, but we knew this is what we wanted and held out for just the right one. All in all, sport wagons are a great but often overlooked alternative to minivans and SUVs. They are incredibly popular in Scandinavia, where my husband is from.
