Well I had the 2006 Nissan Sentra and upgraded by way of a car accident to the 2007. I love the style. It is totally different than the 2006 and resembles the Altima. Nice compact size for myself and I am single with no children but bad choice for someone with a family.
Radio control on the steering wheel.
Folding side mirrors, cruise control, alloys. I have none on my car and the 2006 had more features than the 2007.
