Snow car/van/SUV suggestions?

"Did not the OP say two adults and two kids for a total of 4 people?"

No - I believe this was the info given by the OP:

"I'm looking for a vehicle that is great in snow and can easily transport two kids and two adults. Would like flexibility to carry 2 more kids..."

That adds up to 6 passengers. I prefer Jeep myself. But that's just me.

Ford Flex ... AWD w/ EcoBoost.
A family member has two of them. But remember the best car in the world is going to be crap in the snow unless you put good tires on it ... and that means dedicated snow tires !!
