2012 Nissan Altima Sedan 3.5 SR 4dr Sedan (3.5L 6cyl CVT)
Love the 3.5 SR 
 I recently traded in my 2008 Altima Coupe 2.5S for the 2012 Altima Sedan 3.5 SR. Quite honestly I loved the coupe, it had every option except the navigation, but from an interior size point of view it was inconvenient. It was uncomfortable for adults to sit in the back. So I decided to look into the sedan and ended up purchasing the 3.5 SR with every option, including the navigation system. With a 270 HP engine, it has plenty of power for passing or merging on to the highway. It has a comfortable ride and very good handling and is spacious. The trunk space is huge (especially compared to the coupe). One thing that my 10 year old son pointed out is the interior is very quiet.
