2007 Nissan Sentra Sedan 2.0 SL 4dr Sedan (2.0L 4cyl CVT)
Great car after a year of ownership
 I've had my Sentra SL for a year now, and it has been a great car.  The SL is packed with features that can not be had in most any other 'entry' level vehicle.  (I've never understood why most car designers believe small is always about being the cheapest option and not about preference for many car buyers.)  I've had no issues with the car to date other than something minor at the time of purchase.  I was replacing a 2000 VW Jetta with the Sentra.  I can say, the Sentra does not drive live a Jetta unfortunately, but once you get used it you settle in quickly.  Fuel economy has been about 22-24 in city driving and 36-38 on highway over the year (w/o the air turned on).
