2015 Nissan Sentra Sedan S 4dr Sedan (1.8L 4cyl 6M)
6 speed manual
 I can now speak to the long term aspects as have only owned my car for over two years.  When I bought it I could not find any reviews on gas mileage.  I currently own a 2014 Camry SE.  While not quite as comfortable and roomy as the Camry, it is fun to drive and in the in town mileage is 35.5 mpg.  I like the cruise control location much better on the Sentra and it still is comfortable, quiet and the trunk is roomy for its side.  At 50, it will get will get 50 miles per gallon.  For an inexpensive car, there is no equal. I shopped Corolla, Civic, and Focus. No issues in over 2 years. Great little car to use around town.
