Traded in a Jeep Grand Cherokee (6-cyl) for it. Going from 17 to 29 MPG is a great jump. The ride is comfortable in the city, but with bumpy roads some suspension noise is noticeable. The acceleration is good in the city but the powertrain is not as peppy on the highway; it takes some time to get to the speed you want, but is fine at cruising.
The hybrid system (obviously), and the interior room doesn't seem different than the Grand Cherokee I had. The headroom is fantastic.
Things that would make it better would be to include an auxiliary input (1/8) jack for mp3 players, and maybe a larger 4 cyl. with cylinder deactivation to give one power when needed. Some of these probably have already been addressed in later models.
