A legacy model from Subaru with the styling and finishing of a modern SUV with a station wagon touch up brings about the Outback its design cue. Being on the top 10 best selling SUV of USA, Outback still has to bring more changes to the family like an addition to electric or hybrid option. AWD is a staple feature on all of its model, that is really appreciated. Value for money buy but could do more with the options in engine sizes.
