I have only had this car about a month so I can't say it is broken in by any means and the temperature has been below freezing most of the time. This car meets all my expectations and then some. I was concerned about reading about the "shudder" transition from electric to gas but I found that only noticable at a full stop and not a problem. While driving it is smooth and responsive. I can't wait for warmer weather. On my first tank I hit about 34 mpg which is about the current EPA. I expect in warmer weather that it will improve. Got the tech package and I am glad I did. Seats are a big improvement over the standard cloth. Even now this baby gets me about 15 more per gallon than my previous

I like my Garmen Navigation better than the one on the Altima but it works.
