Comfortable car, but terrible transmission!!
 I received this car brand new (as a new company vehicle), and have now driven it for 7 months and 7k miles.  I'm trying to be as objective as possible here, but I would HIGHLY encourage anyone considering this vehicle to 1) lease it only, or 2) if you purchase it, sell it before the warranty expires because I can guarantee that you will be replacing the transmission between 60,000 and 100k miles (this is a factual statement based on my years of experience working in the auto industry, and frequent experience in dealing with people who own late model Nissan vehicles with failed CVT transmissions - which is what this car has).  If you don't believe me about the CVT transmission issues, please Google "Nissan CVT transmission problems" before buying this car.  There are thousands of complaints at ConsumerAffairs.com regarding Nissan CVT transmissions, and Nissan settled a class-action lawsuit that covered all 2007 to 2010 models (but the problem continues since no significant changes were made to their CVT transmissions following the law suit).  Also, if you buy this car please make sure to budget about $4000 to cover the cost of transmission replacement every 60k to 100K miles.  The problem is so bad that the 2017 Nissan owners manual no longer even recommends a transmission oil change.  The CVT transmission in this car primarily consists of two variable pulleys connected by a metal belt that constantly grinds against the sides of the pulleys to creates friction (and thereby drive the car forward).  As you can imagine, this is a poor and unreliable method of designing a transmission, but it saves money, weight, and results in slightly better fuel economy than a regular transmission.  As you drive, the transmission feels like it's constantly slipping (which it is).  The only time this car feels "normal" is on a flat, open highway at a constant speed with no wind and a light load.  At all other times, the transmission feels like it will survive another 5 miles it it before complete failure.  And that leads me to my next point.  This transmission usually fails without warning, often leaving owners in dangerous situations (imagine it failing on a busy Interstate Highway while you're driving to work, or have your kids in the car).  Never, in a hundred years, would I recommend this car to ANYONE - and anyone with half a brain (or at least some basic automotive knowledge) would not purchase this car due to the well documented history of Nissan CVT transmission problems.   There are some positives to this car (however), including very comfortable front seats, a very good driving position, very good gas mileage (30-31 mpg in mixed driving, and about 38 on the open highway), a well tuned suspension, very good brakes, and a well designed instrument panel and ergonomics.  Unfortunately I cannot (to anyone) recommend this vehicle due to the CVT transmission issue.  Hopefully Nissan listens to its customers and develops a proper 6 to 8 speed automatic transmission (like Toyota, GM, or Ford).  If they did, I would consider this to be a good overall vehicle and a good value.
