 I purchased my car as a family sedan to seat 4, sometimes 5.   The best feature is the interior room and trunk space. The next best feature is fuel economy.   Don't be afraid to get the 6 speed manual transmission. It is smooth as silk and allows you to baby the engine or squeeze some power out when you need to.   I know the CVT auto's claim to fame is better acceleration and economy but at what cost??  The CVT likes to rev the engine up pretty high even below 20 mph just to accelerate faster. I keep the rpm's lower with the 6 speed. And by the way I get above the 35 mpg rated highway mileage cruising on the interstate. On a 400+ mile trip I averaged over 40 mpg at an average speed of 65 mph (traffic slowed me down some). In any event the Sentra 6 speed manual gives you a lot of bang for your buck in a reasonably roomy family sedan.  Don't expect a lot of fancy electronics. Options and controls are basic but uncluttered and easy to operate.
