definitely the jeep. Probably the commander. The vue is small and the nitro is IMPOSSIBLE to see out of. Just my 2 cents. I think that it is great you are looking at American cars instead on some japonese piece of junk.
If you are buying used, and that is what I am assuming from the price range, I would stay away from domestic cars. They have a terrible service records, and their price depreciation is through the roof. Look into Toyota RAV4 or Highlander, Honda CRV, or Mazda CX7
I have a Dodge Durango because we got twins. It's big and has extra seats in back but we keep them down for room for groceries and stuff. It has a lot of room.
