Went from a 2007 Durango Limited to the 2009 xB. We went from 14 mpg to 28 mpg (although to give the Durango credit. Yeah..it has a HEMI!. We weren't sure if we would like something as small as the xB with both of us being "real" sized people. The xB has a lot of room inside and is very comfortable. We have had it for about 2 months and have had no problems at all. It is surprisingly peppy for a 4 cyl and handles great!
Looks, gas mileage, handling, interior size
arm rest on driver's side is not located in a good place, it needs to be higher and out a little so your are will be able to rest on it, need passenger side arm rest also. Radio is nice, but hard to see during daylight
