I like the Wrangler Unlimited, it feels like a Jeep. I'm not sure what the difference in mileage is between the two, so I won't comment there. If you're looking for a good deal; check out craigslist or eBay. Not new, but it will save a lot of money. Wish I could help more.
...I still can't grasp not having 4x4.... on a jeep..... or living here....
