Thanks for all of the info, guys. We've pretty much eliminated the expedition from our search now, unless a low mileage, clean example pops up.
The only real "needs" for the vehicle are more space for storage, more leg room so the kids can no longer kick the rear of the front seats and better inclement weather capability than a neon and a fwd impreza. The venerable Outback has always been the ideal candidate but a suitable, non auto, non dohc, low mileage example has yet to be located.
That and like was said above I've really been craving something rear wheel drive with a V-8 that can haul the family.
