Best cheapest used 4WD or AWD that gets 25+ mpg on highway

Now lets say I take your advice… do I get to call one of you guys when my husband calls me and tells me he is stuck in the snow? Believe me the xd gets blown off the road when a semi passes … what do you guys consider “real” snow tires and which would you recommend… I have to have all my ammo ready… my husband wants to get a Jeep Cherokee which gets 20mpg and I will battle him to the very end to stop that from happening…
