How MUCH better are you looking to get on MPG's? Here's the thing...do the math. The Liberty 4x4 is rated at 15/21. If you are looking at something that claims 19 city/25 highway (built on a car chassis with a 4 cylinder), you won't save you as much money as you think. Based on 1,000 miles/month at average MPG consumption, it's about $20-25 or 2.5 cents/mile. IMO, that's a small price to pay for something truly capable that will tow 5,000 lbs and support your lifestyle. The Rav4, CRV, Element, Escape, Compass, etc. aren't really any less expensive either.
I love my Liberty and I'm easily achieving the sticker MPG and actually doing a little better.
