Wagon, like the Freestar/TaurusX

I'm a wagon fan myself, although more on the compact side than what it sounds like you are interested in. My first (and only) thought was the "not-quite-a-minivan" Mazda5. I don't know what else would have the type of seating you're interested in outside of a minivan or maybe larger SUVs. I'm not sure they offer full leather though.

The wagons I like (A4, 328xi, V50, Jetta) are all small. We have only 1 child (11) plus a big dog (Bernese Mt Dog) and my '07 A4 is tight. I wouldn't want a teenager behind me (6' 0") in the rear seat for a long haul. In a larger size wagon I think you'd end up with a traditional rear seat and your options there are the usual european suspects, Volvo, A6, BMW 5(my father in law loves his V70 with 150K+ miles that he bought used at >100K). There was another wagon post here where the Dodge Magnum was suggested as well.

We've had a Taurus X for the past three years. I like some things about it, but not others. I need to fully write it up. The quick and dirty version...

Likes:
--interior space for people and cargo
--including a deep well behind the third row
--easy to fold seats (unless they jam)
--seat comfort
--great outward visibility
--relatively low price

Dislikes:
--lowest seating position still a little too high
--dangerous to view optional nav, it's so low
--very little feel to the steering
--body motions could be better controlled
--fuel economy lower than expected (close to EPA of 15/22, though)
--reliability so-so (drivetrain seals prone to leaking, second row seat jams, leading edge of hood corrodes)

Would I buy something else today? Probably not, unless we got a minivan. Other non-minivans rarely have enough space for a family's luggage behind the third row. The Honda Pilot might be another exception, but it handles even worse than the Taurus X.
